Embodiment Construction

[0018] Ambulatory medical devices may include one or more of the features, structures, methods, or combinations thereof described herein. For example, a cardiac function management device may be implemented to include one or more of the advantageous features or processes described below. It is intended that such cardiac function management devices or other implantable or partially implantable devices need not include all of the features described herein, but may be implemented to include selected features that provide unique structure or function. Such devices may be implemented to provide various therapeutic or diagnostic functions.

[0019] figure 1 is a diagram of portions of a system including an ambulatory medical device, which is an IMD 110 . Examples of IMD 110 include, but are not limited to, pacemakers, defibrillators, cardiac resynchronization therapy (CRT) devices, or combinations of these devices. In other examples, the IMD is a neurostimulator, such as a vagus ...

Abstract

An apparatus comprises a stimulus circuit, a cardiac signal sensing circuit, and a control circuit. The cardiac signal sensing circuit senses a cardiac activity signal using a sensing channel. The stimulus circuit provides electrical pulse energy to a first pacing channel that includes a first left ventricular (LV) electrode and a second pacing channel that includes a second LV electrode. The control circuit initiates delivery of electrical pulse energy using the first and second pacing channels according to a first multi-site LV pacing mode; determines a cardiac event associated with a changein cardiac conduction path using a sensed cardiac activity signal; and changes to a second LV pacing mode in response to determining the cardiac event. The second LV pacing mode is different from thefirst multi-site LV pacing mode in one or more of a pacing site location and inter-electrode stimulus timing.

Description

[0001] priority claim [0002] This application claims the benefit of priority under 35 U.S.C. §119(e) of U.S. Provisional Patent Application Serial No. 62 / 419,627, filed November 9, 2016, which is hereby incorporated by reference in its entirety. Background technique [0003] Ambulatory medical devices may be used to treat patients or subjects with electrotherapy or other treatments, or to assist physicians or nursing staff in patient diagnosis by internally monitoring the patient's condition. Some types of ambulatory medical devices may be implantable or partially implantable. Some examples include cardiac function management (CFM) devices, such as implantable cardiac pacemakers, implantable cardioverter defibrillators (ICD), cardiac resynchronization therapy devices (CRT), and devices that include combinations of these capabilities . The device may include one or more electrodes in communication with one or more sense amplifiers to monitor cardiac electrical activity with...
