Abstract:
1. A method for controlling automated delivery of therapeutic stimulation pulses by a medical device system including an intracardiac pacemaker implanted in a patient, the method comprising: acquiring by an implantable medical device sensing module a first cardiac signal using a first pair of electrodes selected from a plurality of available electrode pairs that are implanted outside the cardiovascular system, the plurality of available electrodes defining at least one sensing vector that is approximately parallel with a cranial-caudal axis of the patient; generating a first electrocardiogram (ECG) signal from the received first cardiac signal; identifying a P-wave from the ECG signal; transmitting a wireless trigger signal from the implantable medical device to the intracardiac pacemaker in response to identifying the P-wave; and delivering a pacing therapy by the pacemaker in response to the trigger signal.
