Perioperative indications for pacemaker placement:
- any documented symptomatic bradyarrythmia
- a new bundle branch block
- a second degree type II aV block
- a third degree AV block associated with MI
- a bifascicular block in a comatose patient (controversial)
- 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.
