ABSTRACT:
In a dual chamber pacemaker capable of stimulating the atrium and ventricle in a heart, a stimulation pulse in the atrium could be sensed as a ventricular event which cannot be distinguished from a premature ventricular contraction, so the pacemaker institutes a blanking interval in which no sensing occurs and a crosstalk interval in which sensing occurs, detections in the crosstalk interval causing the emission of a ventricular stimulation pulse with a shortened A-V interval. A dual chamber pacemaker and a method for operating same are disclosed wherein the blanking interval is optimized so as to reduce the risk of a PVC being missed and so as also to minimize the number of detected events, caused by crosstalk from the atrium, in crosstalk intervals. This is accomplished by counting, for a number of cardiac cycles, the number of detections in crosstalk intervals and forming a relationship of the count to the number of cardiac cycles. This reduction is then used to determine the length of the blanking interval.
