Patent ID: 7801608

Claim:
A cardiac rhythm management (CRM) system for use in a body having a pulmonary artery connected to a heart, comprising: an implantable pulmonary artery pressure (PAP) sensor adapted to be placed in the pulmonary artery to sense a PAP signal; and an implantable medical device communicatively coupled to the implantable PAP sensor, the implantable medical device including: a pacing circuit to deliver pacing pulses including anti-tachyarrhythmia pacing (ATP) pulses; and an ATP controller coupled to the pacing circuit, the ATP controller including: an ATP delivery controller adapted to control the delivery of the ATP pulses according to an ATP protocol; and an ATP capture verification module adapted to perform an ATP capture verification during the delivery of the ATP pulses by detecting an effective cardiac contraction using the PAP signal, the effective cardiac contraction indicated by a detectable event in the PAP signal.
