Abstract: In a medical device system, a computer apparatus is configured to receive body surface electrical signals from an electrode apparatus including multiple external electrodes. The computing apparatus generates electrical dyssynchrony data from the body surface electrical signals during delivery of His bundle pacing pulses and identifies effective His bundle capture based on the electrical dyssynchrony data. The computing apparatus generates an indication of His bundle capture in response to identifying the effective His bundle capture.

Abstract: Systems and methods are described herein for use in synchronizing electrical activity monitored by a plurality of external electrodes with supplemental cardiac data for use in evaluating a patient's cardiac condition and configuring cardiac therapy. The supplemental cardiac data may include one or more markers indicative of the occurrence of cardiac events and/or data representative of representative of at least one of cardiac electrical signals, cardiac sounds, cardiac pressures, blood flow, and an estimated instantaneous flow waveform provided by a left ventricular assist device.

Abstract: Techniques for evaluating cardiac electrical dyssynchrony are described. In some examples, an activation time is determined for each of a plurality of torso-surface potential signals. The dispersion or sequence of these activation times may be analyzed or presented to provide variety of indications of the electrical dyssynchrony of the heart of the patient. In some examples, the locations of the electrodes of the set of electrodes, and thus the locations at which the torso-surface potential signals were sensed, may be projected on the surface of a model torso that includes a model heart. The inverse problem of electrocardiography be solved to determine electrical activation times for regions of the model heart based on the torso-surface potential signals sensed from the patient.

Abstract: Systems and methods may monitor electrical activity of a patient's heart using electrodes during delivery of cardiac conduction system pacing therapy, generate electrical heterogeneity information (EHI) based on the monitored electrical activity during delivery of cardiac conduction system pacing therapy, and determine whether the cardiac conduction system pacing therapy would benefit from supplemental cardiac pacing therapy based on the generated EHI.

Abstract: VfA cardiac therapy uses an implantable medical device or system. The implantable medical device includes a tissue-piercing electrode implanted in the basal and/or septal region of the left ventricular myocardium of the patient's heart from the triangle of Koch region of the right atrium through the right atrial endocardium and central fibrous body. The device may include a right atrial electrode, a right atrial motion detector, or both. The device may be implanted completely within the patient's heart or may use one or more leads to implant electrodes in the patient's heart. The device may be used to provide cardiac therapy, including single or multiple chamber pacing, atrioventricular synchronous pacing, asynchronous pacing, triggered pacing, cardiac resynchronization pacing, or tachycardia-related therapy. A separate medical device may be used to provide some functionality for cardiac therapy, such as sensing, pacing, or shock therapy.

Abstract: An implantable medical device system is configured to generate signals representing activity of a heart of a patient; determine, based on the signals, an intrinsic delay of the heart of the patient; determine whether the intrinsic delay is indicative of a first-degree heart block being present in the heart of the patient; determine a patient-specific timing regime for conduction system pacing based on whether the intrinsic delay is indicative of the first-degree heart block being present in the heart of the patient; and administer cardiac pacing to a native conduction system of the heart of the patient based on the timing regime.
