Hermann D Funke, Lodewijk Jozef Herpers: Ventricular synchronized atrial pacemaker and method of operation. Medtronic B V Kerkrade, Joseph F Breimayer, Lew Schwartz, Robert C Beck, August 18, 1981: US04284082 (21 worldwide citation)

An atrial pacemaker having an atrial pacing rate adjusted to correspond to a detected ventricular heart rate to maintain A-V synchrony in a range between a minimum and maximum pacing rate. Sensed ventricular depolarizations not associated with a preceding atrial pacing stimulus cause the atrial paci ...
