Monitoring 12-Lead ECG
The Propaq MD 12-Lead input is Type CF defibrillator proof.
This chapter describes how to use the Propaq MD unit to perform 12-Lead ECG Monitoring.
The Propaq MD with the 12-lead ECG Monitoring option provides simultaneous acquisition
and storage of 12-lead information.
Warning! • 12-Lead ECG monitoring is intended for the recording of 12-lead ECG signals
acquired from adult and pediatric patients in the supine, resting position -- always
ensure that the patient is kept motionless during 12-lead ECG signal acquisition. Use of
the device to acquire ECG signals from moving or shaking patients may produce noisy
signals that are difficult to interpret.
• Excessive body hair or wet, sweaty skin may interfere with electrode adhesion. Remove
the hair and/or moisture from the area where the electrode is to be attached.
• Remove ECG electrodes from their sealed package immediately prior to use. Using
previously opened or out-of- date electrodes may degrade the ECG signal quality.
• Monitoring electrodes may become polarized during defibrillator discharge, causing
the ECG waveform to briefly go off screen. ZOLL Medical Corporation recommends
the use of high quality silver/silver chloride (Ag/AgCl) electrodes to minimize this
effect; the circuitry in the instrument returns the trace to the monitor display within a
few seconds.
• Wait 15 seconds after defibrillator discharge before attempting a 12-lead acquisition.
Electrode polarization subsequent to defibrillator discharge may result in excessive
noise on the 12-lead ECG printout.
