A method of pacing a congestive heart failure (CHF) patient's heart using a pacemaker typically capable of bradycardia dual chamber pacing. The method includes an algorithm for resetting the timing interval of the microprocessor based controller of the pacemaker for stimulating the ventricles after a predetermined AV delay, when a legitimate signal associated with atrial events is blocked by a preprogrammed Post Ventricular Atrial Refractory Period (PVARP).
