AV Sequential or DDD Pacemakers
For pacemaker patients, follow these steps:
z
Always attach at least four electrodes to allow for a choice of leads.
z Turn pacer detection on.
z Select the lead with the highest R-wave and the least interference.
z Verify that the HR calculation is accurate by comparing it to the ECG
waveform.
z Monitor the pulse or the respiration or both using a method other than ECG.
For patients without pacemakers, turn the pacer detection off.
