Estimating the term…
Methods, devices, and systems for performing pacing capture verification in implantable medical devices such as a leadless cardiac pacemakers using a pressure signal. An example medical device includes a pressure sensor and is configured to monitor for an evoked capture response using the pressure sensor following pace delivery. Various factors of the pressure waveform may be used including the use of threshold, templating, and slope, as well as comparing cross-domain sensed events including using a fiducial point from the pressure signal for comparison to an acoustic, electrical, or motion event, or the use of data obtained from a second device which may be implanted, wearable, or external to the patient.
An implantable medical device in the form of a cardiac pacemaker, comprising:
An implantable medical device in the form of a cardiac pacemaker, comprising:
A method of verifying pacing capture in an implantable cardiac pacemaker comprising at least first and second electrodes for at least one of delivering therapy or sensing electrical signals, a pressure sensor for sensing intracardiac pressure, operational circuitry coupled to the electrodes and the pressure sensor, and a housing sized and adapted for placement in or on the heart of a patient, the housing containing at least the operational circuitry;
