Abstract
A method of employing an implantable medical device to detect pacemaker mediated tachycardia (PMT) and adjusting a parameter (e.g. PVARP) in response to confirmation of the PMT. The method comprises, with a processor located in the implantable medical device, (1) measuring a first Vp-As (VA1), (2) lengthening SAV by 50 ms for 1 beat in response to measuring VA1, (3) measuring a second Vp-As (VA2), (4) returning to a normal SAV, (5) measuring a third Vp-As (VA3), (6) determining whether VA1=VA2 and VA1=VA3, (7) in response to determining whether VA1=VA2 and VA1=VA3, confirming presence of PMT, and (8) in response to confirming presence of PMT, PVARP is extended.
