Do not touch the patient while touching any metal part of non-medical electrical equipment or an exposed part when a connector or cover is removed. Failure to follow this warning may cause electrical shock or injury to the patient.
Do not connect the tip of the electrode lead to anything other than an electrode. Connect all the tips to the corresponding electrodes and attach them to the patient. If unconnected tips or electrodes contact an item which is not equipotential grounded, the patient may receive electrical shock. Also, noise may superimpose on the ECG waveforms and measurement data may be incorrect.
CAUTION
CAUTION
Enter the patient information correctly. Otherwise, the ECG data may be lost or mixed up with another patient’s ECG data. When managing examination data that is only in electronic file, make sure to enter the patient information.
Do not use the output signal from the output connector of the electrocardiograph for a synchronization signal on a defibrillator. There is a time delay between the input signal and output signal. When using the output signal from the electrocardiograph for the synchronization signal on other instrument, always consider this time delay.
CAUTION The paper cutter in the recording paper container is sharp. When setting the recording paper, be careful not to cut your finger. Set the recording paper as specified.

1. GENERAL ECG Recording Judgement
CAUTION • The automatic ECG interpretation is performed for acquired ECG waveforms only and does not reflect all conditions of the patient. The results of the analysis might not correspond to the judgement of a physician. • Overall judgement must be performed by the physician, referring to the analysis result, clinical findings, and other examination results. After the physician’s overall judgement, the analysis results should be signed or initialed by the physician.
1 CAUTION Take care when judging the ECG recording because the EMG filter may cause distortion of P-waves and QRS-waves depending on the waveform shape.
Maintenance CAUTION Before maintenance, cleaning or disinfection, turn the electrocardiograph power off and disconnect the power cord from the AC socket. Failure to follow this instruction may result in electrical shock and electrocardiograph malfunction.

Connecting the Power Cord and Grounding the 2
Electrocardiograph Connecting the Power Cord WARNING Only use the provided power cord. When the provided power cord cannot be used or when equipotential grounding is doubtful (such as in a facility with poor grounding), operate the electrocardiograph on battery power. Otherwise, the patient and operator may receive electrical shock or injury. NOTE • Make sure that there is always a battery pack inside the electrocardiograph in case the power cord is disconnected or there is a power failure. • When there is no battery inside the electrocardiograph, there may be noise on the waveform or the electrocardiograph may reset and lose measurement data. Connect the provided power cord to the AC power cord socket on the right side panel of the electrocardiograph and plug the cord into a 3-prong AC socket.
Grounding the Electrocardiograph WARNING When several medical instruments are used together, ground all instruments to the same one-point ground. Any potential difference between instruments may cause electrical shock to the patient and operator.
When more than one electrical instrument is used, there may be electrical potential difference between the instruments. The potential difference between the instruments may cause current to flow to the patient connected to the instruments, resulting in electrical shock (micro shock). Always perform equipotential grounding when required. It is often required in the operating room, ICU room, CCU room, cardiac catheterization room and Xray room. Consult with a biomedical engineer to determine if it is required. When equipotential grounding is required to ensure patient safety, use the grounding wire of the AC power cord.

• Organic solvents and plastics may develop color on the white surface or cause the recording paper to fade. Examples of color-developing materials containing organic solvents: Adhesives, paste, felt-tip pens, and semi-dry diazo paper. Examples of color-fading materials made of soft vinyl chloride: Document cases, albums, and desk pads including. Examples of color-fading materials containing plastics: Erasers, adhesive tapes, and some fluorescent pens. • The paper cutter in the recording paper container is sharp. When setting the recording paper, be careful not to cut your finger. Set the recording paper as specified. • When pasting the recording paper, use paste with a starch base, PVA base, arabic gum base paste, CMC base synthetic paste, or paper bond. • Do not apply high pressure to the recording paper. Rubbing or scratching the surface with a hard object discolors it. • Clean the thermal head with the thermal head cleaner after every 100 m printing. A dirty thermal head degrades printing quality. • Do not use recording paper which is contaminated with ECG electrolyte cream (cardioCream) or saline solution because the recording paper will fade by the chloride and the contaminated thermal head may cause missing dots. If the thermal head gets contaminated, clean it with the thermal head cleaner pen. • Do not touch the thermal head with your fingers. If accidentally touched, clean the thermal head with the thermal head cleaner pen. • Follow the procedure to set the recording paper. Otherwise, the recording paper might not feed normally or the feeding motor may stop operation.
Replacement
CAUTION Do not set the recording paper right after recording because the thermal head is still hot.

4. ATTACHING THE ELECTRODES AND ENTERING PATIENT INFORMATION
WARNING Do not connect the tip of the electrode lead to anything other than an electrode. Connect all the tips to the corresponding electrodes and attach them to the patient. If unconnected tips or electrodes contact an item which is not equipotential grounded, the patient may receive electrical shock. Also, noise may superimpose on the ECG waveforms and measurement data may be incorrect.
CAUTION • Do not use new and old electrodes together, or re-usable and disposable electrodes together (such as clip electrodes, suction electrodes, and disposable electrodes). If different types are used together, it may cause a high polarization voltage and prevent displaying and recording of the ECG waveforms. • Always replace all the electrodes with new ones at the same time. • When using an ESU and defibrillator with the electrocardiograph, use silver chloride disposable electrodes. • Only use clean and undamaged electrodes with no scratches on the surface. Electrodes with a deteriorated surface may cause high contact impedance and distorted ECG waveforms. • Do not touch electrodes, lead tips or electrocardiograph connectors to any other ground or conductive object in the room, such as a metal bedpost.

Error Indication When the Electrode Is Not Attached Firmly Screen Message The electrocardiograph continuously checks electrode attachment status. When electrode detachment or large polarization voltage is detected, a message is displayed. Screen message Fail R, L, F Fail Limb Fail 1, 2, 3, 4, 5 or 6 Noise
Possible cause The indicated limb electrode is detached. • Two or more limb electrodes from the R, L or F electrode are detached. • The RF electrode is detached. • No electrode is attached to the patient. The indicated chest electrode is detached. Noise or artifact is detected.
NOTE • If a limb electrode is detached, the chest electrode detachment message is not displayed. Check the chest electrode attachment after removing the cause of the error message. • The ECG waveforms can be displayed and recorded if the message due to a large polarization voltage is displayed. If recording starts, the analysis result may be incorrect and the ECG waveforms cannot be saved. Remove the cause of the error message before starting measurement. • A flat baseline is recorded for leads with a detached electrode. • When using the electrocardiograph with an ESU, artifact from the ESU may be superimposed on the ECG waveforms.

Electrode detachment
Noise
Countermeasure Electrode Detachment Check for detached electrodes corresponding to the message and the electrode lead. Reattach the electrode and connect the electrode lead. Large Polarization Voltage If the message is still displayed after reattaching the electrode, it is probably due to a large polarization voltage. A large polarization voltage can have the following causes: • New and old electrodes, or re-usable and disposable electrodes are used together (such as clip electrodes, suction electrodes, and disposable electrodes). If different types are used together, it may cause a large polarization voltage and prevent displaying and recording of the ECG waveforms. • Improper skin preparation. Use a cotton moistened with alcohol to clean the skin where the electrode is attached and apply the electrolyte cream (cardioCream) on the clean skin site. Reattach the electrode. • After defibrillation, the ECG waveforms become unstable. Wait at least 5 seconds until the ECG waveforms are stable before recording the ECG waveforms. When the cause of the message cannot be found, the electrode lead may be faulty. If any abnormality is found, refer to “Troubleshooting” in Section 8 to take proper action. If there is any damage or the electrocardiograph is suspected to be faulty as a result of checking, attach an “Unusable” or “Repair request” label to the electrocardiograph and contact your Nihon Kohden representative.

5. RECORDING RESTING ECG WAVEFORMS
General You can record the resting ECG waveforms automatically or manually. When the power is turned on, automatic recording mode is the default selection. In automatic recording mode, ECG analysis is automatically performed. After ECG waveforms are recorded, the ECG analysis result is automatically printed (unless “Report print out” setting is set to Off on the System Setting screen). There are two automatic recording modes, real time and review recording mode. In review recording mode, you can verify the ECG waveform displayed on the screen before starting recording. This lets you confirm clear ECG recording and accurate ECG analysis. In real time recording mode, when fluctuation of 20% of R-R interval is detected, the electrocardiograph can automatically extend lead group recording for the preset interval. After recording, you can save the 12 lead ECG (including extended sequence recording) analysis result and patient information as an ECG data file in the media. You can make one or more copies of the recording results before the next recording starts. In manual recording mode, you can manually change the recording settings (paper speed, sensitivity, and EMG filter on/off) during recording. You can also annotate the ECG waveforms with an event mark by pressing the FEED/MARK key. Before or after automatic or manual ECG recording, you can record one minute of the rhythm lead. You can set the channel of the lead on the Rhythm Recording of the Recording Settings in the Main Setup screen. For recording settings and other settings, refer to Section 3 “Changing Settings Before Measurement”. Caution when the ECG waveform has artifact
CAUTION During recording, if large artifact appears on the ECG waveform, immediately stop the recording and remove the cause of the artifact. Refer to “Troubleshooting” in Section 8. Failure to follow this instruction causes overheating and damage to the electrocardiograph.
If the ECG recording is continued in this condition, the power unit in the electrocardiograph generates high frequency noise which causes the electrocardiograph to heat up. When the electrocardiograph heats up, a notification sound occurs and the START/STOP lamp blinks. The recording cannot be performed until the electrocardiograph cools down. 5.2

5. RECORDING RESTING ECG WAVEFORMS
Notes for Accurate Measurement Before Starting the Recording 1. In order to acquire correct heart rate and accurate analysis result, confirm the following before pressing the START/STOP key. • Stable heart rate • No electrode detachment or noise message • The QRS sync mark on the screen blinks in synchronization with the QRS sound or pen sound. To generate the sound, refer to “System Settings” in Section 3. • No artifact in the pen sound. 2. Immediately after electrodes are attached, the ECG waveforms may be unstable because of polarization voltage. Before pressing the START/STOP key wait at least 10 seconds for stable ECG waveforms.
Detecting QRS Waves The electrocardiograph detects the QRS wave from leads II, V1 and V5. To assure QRS detection accuracy, take care to minimize superimposed artifact on these leads. Take care that QRS wave detection accuracy is not reduced by artifact superimposed on these leads. Also when the amplitude of these QRS waves is too small (less than 0.5 mV), the electrocardiograph cannot detect the QRS wave. NOTE If low amplitude QRS wave is displayed on the screen and the QRS sync mark does not blink, the electrocardiograph does not analyze the ECG waveform. The “CANNOT ANALYZE ECG” message is printed on the ECG analysis result.
Counting the Heart Rate The electrocardiograph counts the heart rate by averaging the latest five QRS waves and prints the heart rate together with the ECG waveforms.
Using the EMG/High-cut Filter When using the EMG filter, the quality of ECG recording may be reduced. However, the EMG filter and high-cut filter do not affect the ECG analysis.
5.4
Operator’s Manual ECG-1150
5. RECORDING RESTING ECG WAVEFORMS
ECG Analysis The electrocardiograph acquires 12 lead ECG waveforms simultaneously and analyzes the 10 to 24 seconds of ECG waveforms. The selected leads and interval of the waveforms are printed on the paper. The ECG analysis result is incorrect if artifact is superimposed on the notselected leads or interval. When an electrode detachment line or noise line is printed on the paper, artifact was superimposed on the ECG waveforms during acquisition. When any of these line is printed, record the ECG waveforms again to assure accurate ECG analysis, verifying that all ECG leads are free from artifact.

5. RECORDING RESTING ECG WAVEFORMS
Automatic Recording General The electrocardiograph automatically records the ECG waveforms and calibration waveforms by switching the lead groups in the settings selected in the Setup mode when the START/STOP key is pressed. There are two recording modes: Real Time Recording When you press the START/STOP key, the electrocardiograph starts recording real time ECG waveforms following the Auto Recording settings in the Setup mode. The ECG lead group is periodically switched. When “Auto start” is set to “On” on the Auto Recording of the System Setup screen and auto-start conditions are satisfied, real time recording automatically starts. Review Recording When the Resting ECG mode is selected, the electrocardiograph checks for electrode detachment. When 2 seconds pass with no electrode detachment, the electrocardiograph starts acquiring and saving the ECG waveforms. So you can check the acquired ECG waveforms before recording starts. When the F3 function key is pressed, the electrocardiograph starts recording the saved waveforms from 10 seconds before the F3 function key is pressed. Auto Gain and Auto Position The recording sensitivity and position are automatically adjusted so that the ECG waveforms of each channel do not overlap. However, waveforms may overlap where there is noise or change of waveform. During recording, if any ECG waveforms exceed the maximum recording width, the waveform amplitude is automatically reduced to 1/2 (up to 1/8) and the waveforms are repositioned so that the entire waveforms can be recorded on the recording paper. The auto gain waveform amplitude is based on the sensitivity setting before recording.
Preparation for Automatic Recording Change the following settings, if necessary. Refer to Section 3 “Changing Settings Before Measurement”. The factory default settings are underlined. To print out the current settings, refer to “Printing the List of System Setup and Main Setup Settings” in Section 3.

Recording Clear ECG Waveforms AC Interference Appears on the ECG as even-peaked, regular voltages superimposed throughout the tracing. It may appear in conjunction with muscle tremor.
Causes: • Dirty or corroded lead wire tips or electrodes • Loose electrode connection • Patient or technician touching an electrode during recording • Patient touching any metal part of a bed or examination table • Broken lead wire, patient cable or power cord • Electrical devices in the immediate area, lighting, concealed wiring in walls or floors • Improperly grounded electrical outlet
Muscle Tremor Interference (EMG) Appears on the ECG as random, irregular voltages superimposed on the tracing. It may resemble or occur in conjunction with AC interference.
Causes: • Patient is uncomfortable, tense, nervous or apprehensive • Patient is cold and shivering • Patient has a neurological or muscular disorder (e.g. Parkinson’s Disease) • Examination table or bed is too narrow or short to support limbs comfortably

8. TROUBLESHOOTING AND ERROR MESSAGES
Wandering Baseline Appears on the ECG as a fluctuation of the tracing up and downward on the grid.
Causes: • Dirty or corroded electrodes • Loose electrodes or electrodes positioned on a bony area • Insufficient or dried out cardioCream • Oily skin or body lotions and creams • Rising and falling of chest during normal or apprehensive respiration
8
When wandering baseline occurs: • Clean skin with alcohol or acetone if necessary • Reposition electrodes • Check the electrode connections • Have the patient relax
Abnormal Printout During ECG recording, loose or poor electrode contact causes waveform saturation, excessive AC interference, etc. In this case, the electrocardiograph stops printing to protect the thermal head. Check the electrode attachment.

8. TROUBLESHOOTING AND ERROR MESSAGES
Other When an electrosurgical unit (ESU) is used with the electrocardiograph, noise generated by an ESU is superimposed on the ECG waveforms. Equipment in the same room as the electrocardiograph may generate noise on the ECG waveforms. • Noise from an electrosurgical unit • Noise from the AC power line • Spike noise caused by electrostatic energy as shown below. The ECG may interpret the noise spike as a QRS or pacemaker spike.
NOTE The baseline becomes flat for a while after defibrillation to protect the electrocardiograph.
