ABSTRACT:
An improved atrial synchronous, dual-chamber pacemaker provided with a variable refractory period during which the pacemaker is not responsive to sensed atrial contractions. The atrial refractory period is selected based upon whether the ventricular pacing pulse preceding the refractory period occurred as a result of time out of the interval corresponding to the basic ventricular pacing rate or due to the time out of the A-V delay interval initiated in response to sensing of a natural atrial contraction.
