Embodiment Construction

[0046] Systems, devices, and methods for pacing cardiac conducting tissue are disclosed herein. Embodiments of the system may include an electrical stimulator for generating His bundle pacing (HBP) pulses for delivery at or near the His bundle. The system can sense a far-field signal representing a ventricular response to an HBP pulse, and detect a His bundle response and a myocardial response from at least the far-field signal. The system can classify tissue responses to HBP into one of multiple capture types. In one example, the classification of tissue response can be based on sensed near-field cardiac activity and sensed far-field cardiac activity. The system can adjust one or more stimulation parameters based on the His bundle response and the myocardial response or the classified capture type, and deliver HBP pulses to excite the His bundle according to the adjusted stimulation parameters.

Abstract

Systems and methods for pacing cardiac conductive tissue are described. A medical system includes electrostimulation circuit that may generate His-bundle pacing (HBP) pulses for delivery at or near the His bundle. A capture verification circuit may detect, from a far-field signal representing ventricular response to the HBP pulses, a His-bundle response representative of excitation of the His bundle directly resulting from the HBP pulses, and a myocardial response representative of excitation of the myocardium directly resulting from the HBP pulses. A control circuit may adjust one or more stimulation parameters based on the His-bundle response and myocardial response. The electrostimulation circuit may generate and deliver the HBP pulses according to the adjusted stimulation parameters toexcite the His bundle.

Description

[0001] priority claim [0002] This application requires U.S. Provisional Patent Application Serial No. 62 / 580,711 filed November 2, 2017, U.S. Provisional Patent Application Serial No. 62 / 595,535 filed December 6, 2017, and 2017 under 35 U.S.C. § 119(a) Priority benefit of U.S. Provisional Patent Application Serial No. 62 / 595,541, filed December 6, the entire contents of which are hereby incorporated by reference. technical field [0003] This document relates generally to medical systems, and more particularly to systems, devices, and methods for pacing cardiac conduction tissue, such as the bundle of His. Background technique [0004] The heart is the center of the human circulatory system. It includes an electromechanical system that performs two primary pumping functions. The left half of the heart, including the left atrium (LA) and left ventricle (LV), draws oxygenated blood from the lungs and pumps it into the body's organs to provide the organs with their metaboli...
