Pacemaker
Indications
Special situations when placement of permanent pacemakers is indicated in first degree heart block are:
- Hemodynamic compromise
- Pacemaker syndrome (loss of atrioventricular synchrony)
- Some neuromuscular conditions associated with first degree heart block such as
Contraindications
- Asymptomatic first degree heart block
A dual chamber DDD pacemaker is preferred over a single chambered VVI pacemakers as it maintains physiologic AV synchrony. A dual-chamber artificial pacemaker is a type of device that typically listens for a pulse from the SA node and sends a pulse to the AV node at an appropriate interval, essentially completing the connection between the two nodes. Pacemakers in this role are usually programmed to enforce a minimum heart rate.
