Andrew P Kramer, Jeffrey E Stahmann, Rene H Wentkowski, Kenneth L Baker, Jesse W Hartley, David B Krig: System providing ventricular pacing and biventricular coordination. Cardiac Pacemakers, Schwegman Lundberg Woessner & Kluth P A, September 4, 2001: US06285907 (294 worldwide citation)

A cardiac rhythm management system includes techniques for computing an indicated pacing interval, AV delay, or other timing interval. In one embodiment, a variable indicated pacing interval is computed based at least in part on an underlying intrinsic heart rate. The indicated pacing interval is us ...
