What are the differences between single and dual chamber
For single chamber pacing, either the right atrium (upper chamber) or the right ventricle (lower chamber) is paced. Only one pacing lead is used. For dual chamber pacing, both the right atrium and right ventricle are paced. This requires two pacing leads. One lead is placed in the right atrium, and the other lead is placed in the right ventricle. ...read more
Types of Pacemakers - Bradycardia | Medtronic
Single- and dual-chamber pacemakers with multiple pacing modes (VVI, DDD, DDI, and VOO, among others) were developed (Table 1.2). Hysteresis was added to maximize native ventricular capture in patients with single-chamber ventricular pacemakers. Although dual-chamber pacemakers had distinct advantages, there was the problem of pacemaker ...read more
