Guide to the use of Artificial Pacemakers

Abstract

In comparison with the fixed-rate pacemaker, the demand type of artificial pacemaker has the advantage of avoiding competition between natural and pacemaker rhythms. Demand pacemaker function can be tested with a special external device that temporarily speeds the rate. Atrial-synchronized pacemakers have recently gained favor because they can meet varying physiologic requirements and thus are well suited to young, active persons.
