Abstract
An implantable medical device system includes an extracardiac sensing device and an intracardiac pacemaker. The sensing device senses a P-wave attendant to an atrial depolarization of the heart via housing-based electrodes carried by the sensing device when the sensing device is implanted outside the cardiovascular system and sends a trigger signal to the intracardiac pacemaker in response to sensing the P-wave. The intracardiac pacemaker detects the trigger signal and schedules a ventricular pacing pulse in response to the detected trigger signal.
Claims21
A medical device system comprising:
- a first implantable medical device comprising:
- first sensing circuitry configured to detect a signal transmitted by a second implantable medical device;
- a power source comprising at least one battery;
- and
- a pulse generator configured to:
- receive power from the at least one battery for generating a pacing pulse;
- and
- deliver the pacing pulse in response to the first sensing circuitry detecting the transmitted signal.
A method comprising:
- detecting, by a first implantable medical device, a signal transmitted by a second implantable medical device;
- and
- delivering a pacing pulse to a first heart chamber in response to detecting the transmitted signal by powering a pulse generator of the first implantable medical device from at least one battery of the first implantable medical device to generate the pacing pulse.
Non-transitory computer readable media storing instructions that, when executed by control circuitry of a medical device system, cause the medical device system to:
- detect by a first implantable medical device of the medical device system, a signal transmitted by a second implantable medical device of the medical device system;
- and
- deliver a pacing pulse in response to detecting the transmitted signal by powering a pulse generator of the first implantable medical device from at least one battery of the first implantable medical device to generate the pacing pulse.
