A multi-site atrial pacemaker capable of delivering pacing pulses to one location synchronized to sensed or paced atrial depolarizations on another location and a method of its use. A defined interval is defined following atrial depolarizations during which such synchronized atrial pacing pulses may not be delivered. The pacemaker automatically adjusts the duration of the defined interval to produce a minimum level of induced tachyarrhythmias. Generally, this desired result is accomplished by measuring coupling intervals of PACs, monitoring occurrences of atrial tachyarrhythmias associated with PACs and adjusting the defined interval accordingly.
