Abstract: An implantable medical device system receives a cardiac electrical signal produced by a patient's heart and comprising atrial P-waves and delivers a His bundle pacing pulse to the patient's heart via a His pacing electrode vector. The system determines a timing of a sensed atrial P-wave relative to the His bundle pacing pulse and determines a type of capture of the His bundle pacing pulse in response to the determined timing of the atrial P-wave.

Abstract: A medical device is configured to receive a cardiac signal and determine a morphology matching score from the cardiac signal and a capture detection morphology template that corresponds to a first type of cardiac pacing capture that includes capture of at least a first portion of the His-Purkinje system. The device is configured to detect a second type of cardiac pacing capture in response to the morphology matching score being less than the first match threshold. The second type of cardiac pacing capture is different than the first type of cardiac pacing capture and may include capture of the ventricular myocardium and/or a second portion of the His-Purkinje system different than the first portion.

Abstract: An IMD system receives a near field His bundle electrical signal produced by a patient's heart via a first sensing electrode vector and a far field cardiac electrical signal via a second sensing electrode vector different than the first sensing electrode vector. The IMD system generates His bundle pacing pulses delivered to the patient's heart via a His pacing electrode vector and determines a type of cardiac capture evoked by a His bundle pacing pulse.

Abstract: A medical device is configured to sense a cardiac electrical signal and determine from the cardiac electrical signal at least one of a maximum peak amplitude of a positive slope of the cardiac electrical signal and a maximum peak time interval from a pacing pulse to the maximum peak amplitude. The device is configured to determine a capture type of the pacing pulse based on at least one or both of the maximum peak amplitude and the maximum peak time interval.
