Indications for Temporary Pacing in Acute Myocardial Infarction
- Asystole (after restoration of spontaneous rhythm)
- Complete heart block
- Right bundle branch block with new left anterior hemiblock or left posterior hemiblock*
- New left bundle branch block
- Mobitz type II second-degree AV block
- Mobitz type I (Wenckebach) second-degree AV block with hypotension not responsive to atropine
- Sinus bradycardia with hypotension or recurrent sinus pauses not responsive to atropine
- Atrial or ventricular overdrive pacing for recurrent ventricular tachycardia (seek advice from a cardiologist)

* Left anterior hemiblock gives left axis deviation (S wave > R in lead II); left posterior hemiblock gives right axis deviation (S wave > R in lead I).
