ECG Monitoring: Pacemaker Troubleshooting
Problem: Inaccurate pacemaker
detection
Solution: Use pacemaker processing:
1. Click on the patient’s ECG tab.
2. In the Detect Pace section, select either Pace 1 or Pace 2.
Notes:
 In general, BE AWARE that a pacemaker pulse could be falsely
counted as a QRS during asystole.
 Pace 1 mode analyzes the presence of a pacer spike, assesses the
waveform for residual pacemaker energy, and determines the
presence of an R wave following the pacer spike. If an event occurs
during the first few milliseconds following the pacer spike, it will be
counted.
 Pace 2 mode analyzes waveforms with the added capability of
minimizing the chance of counting severe residual pacemaker energy
as QRS complexes. In relation to the event rejection capability of
Pace 2 pace mode, certain morphologies may not be detected.
Arrhythmia calls like asystole or pause may be made with heart rate
identified as less than actual.
Again, pacemaker patients should be kept UNDER CLOSE
OBSERVATION. The appropriate pace mode may be determined at the
time the pacemaker patient is admitted to the monitoring system. The
Pace 2 mode is recommended for use whenever possible.
Check ECG signal from patient:
1. Check/adjust lead placement.
2. Check/perform skin preparation.
3. Check/replace electrodes.
