Indications for temporary transvenous cardiac pacing
| Emergency/acute |
| Acute myocardial infarction: (Class I: ACC/AHA)3 |
| • Asystole |
| • Symptomatic bradycardia (sinus bradycardia with hypotension and type I 2nd degree AV block with hypotension not responsive to atropine) |
| • Bilateral bundle branch block (alternating BBB or RBBB with alternating LAHB/LPHB) |
| • New or indeterminate age bifascicular block with first degree AV block |
| • Mobitz type II second degree AV block |
| Bradycardia not associated with acute myocardial infarction |
| • Asystole |
| • 2nd or 3rd degree AV block with haemodynamic compromise or syncope at rest |
| • Ventricular tachyarrhythmias secondary to bradycardia |
| Elective |
| • Support for procedures that may promote bradycardia |
| • General anaesthesia with: |
| 2nd or 3rd degree AV block |
| Intermittent AV block |
| 1st degree AV block with bifascicular block |
| 1st degree AV block and LBBB |
| • Cardiac surgery |
| Aortic surgery |
| Tricuspid surgery |
| Ventricular septal defect closure |
| Ostium primum repair |
| Rarely considered for coronary angioplasty (usually to right coronary artery) |
| Overdrive suppression of tachyarrhythmias |
