Pacemaker Patients / Recording During Defibrillation: Recording ECGs of Pacemaker Patients

Recording ECGs of Pacemaker Patients

Due to the slow paper speed, it is not possible to display pacer pulses 
directly on the ECG recording. At a paper speed of 50 mm/s and a pulse 
duration of only 0.5 ms, the width of the recorded pacer pulse would be 
only 0.025 mm.

For this reason, the recorder reduces the pulse amplitude and expands 
the pulse width, so that the pacer pulse is easier to identify. The MAC 
1200 records the pulse with the correct polarity, with a width of 5 ms and 
with the same amplitude in all leads (depending on the polarity of the 
pacer pulse in leads I and II, the pacer pulse in lead III may be 
suppressed) The amplitude of the reverse current in the figure below 
shows an ECG recording with pacer pulses.

ECG Recording with Pacer Pulses

:$51,1*

INCORRECT HR, NO HR ALARM — If several adverse 
conditions exist at once, the possibility that the pacer pulses 
are interpreted (and counted) as QRS complexes should be 
considered. At the same time, however, QRS complexes 
might be suppressed in certain situations. Therefore, 
pacemaker patients should always be watched closely.
