3.8. Verifying Proper Pacemaker Handling
For paced patients, proper electrode placement results in pacer tick marks along
the top of each ECG waveform channel on the Nightingale PPM3 and the MPC.
These tick marks occur at the point where the PPM3 detects a pacer pulse.
The PPM3 rejects pacer pulses rather than calling them QRS’s (per IEC 60601-2-
27). However, it is important to keep paced patients under close surveillance and
not to entirely rely on rate meters for these patients (as indicated in the warning at
the start of this manual).
