MICROPROCESSOR TYPE CARDIAC PACE MAKER AVOIDING FREQUENT PULSE STATE LASTED BY PACER

摘要

A microprocessor-controlled pacemaker is programmed to extend an atrial refractory interval in response to the detection of events which could initiate a pacer sustained tachycardia. The extended atrial refractory interval ensures that a spurious atrial event resulting from retrograde conduction of a ventricle event will not cause a pace of the ventricle.
