Embodiment Construction

[0064] The following description should be read with reference to the drawings in which like elements in different drawings are numbered the same. The specification and drawings, which are not necessarily to scale, depict exemplary embodiments and are not intended to limit the scope of the present disclosure. While the present disclosure applies to any suitable implantable medical device (IMD), the following description uses a pacemaker, and more particularly a leadless cardiac pacemaker (LCP), as a specific example.

[0065] All numbers herein are assumed to be modified by the term "about", unless the content clearly dictates otherwise. Recitations of numerical ranges by endpoints include all numbers subsumed within that range (eg 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5).

[0066] As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the content clearly dictates otherwise. As used in this sp...

Abstract

A ventricularly implantable medical device that includes a sensing module that is configured to detect an artifact during ventricular filling and to identify an atrial event based at least on part onthe detected artifact. Control circuitry of the implantable medical device is configured to deliver a ventricular pacing therapy to a patient's heart, wherein the ventricular pacing therapy is time dependent, at least in part, on the identified atrial event.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application 62 / 593,642, filed December 1, 2017, the disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates generally to implantable medical devices and, more particularly, to systems for monitoring, pacing, and / or defibrillating a patient's heart using a leadless cardiac pacemaker. Background technique [0004] Implantable medical devices are commonly used today to monitor and / or deliver therapy to patients. For example, in some cases, pacing devices are used to treat patients with various heart conditions that can reduce the heart's ability to pump adequate amounts of blood into the patient's body. Such heart conditions may cause slow, rapid, irregular and / or ineffective contractions of the heart. To help alleviate some of these conditions, various medical devices (eg, pacemakers, defibrillators, ...
