Cardiac pacemaker indications

Perioperative indications for pacemaker placement:

1. any documented symptomatic bradyarrythmia
2. a new bundle branch block
3. a second degree type II aV block
4. a third degree AV block associated with MI
5. a bifascicular block in a comatose patient (controversial)
6. refractory supraventricular tachyarrhythmias

Indications 1-5 generally require ventricular pacing. Refractory supraventricular tachyarrhythmias will require atrial pacing electrodes and a programmable rapid atrial pulse generator.
