Abstract
The present disclosure relates generally to pacing of the cardiac conduction system of a patient, and more particularly, to providing adaptive cardiac conducting system pacing therapy and to determining selective or non-selective capture of the cardiac conduction system by cardiac conduction system pacing therapy. The adaptive cardiac conduction system pacing therapy may adjust AV delay and VV delay based on various signals and metrics and may switch between cardiac conduction system pacing therapy exclusively and cardiac conduction system pacing therapy in combination with traditional left ventricular pacing therapy.
Claims20
An implantable medical device comprising:
- a plurality of implantable electrodes to sense and pace a patient's heart, wherein the plurality of electrodes comprises:
- a left ventricular electrode positionable proximate the patient's left ventricle;
- and
- a cardiac conduction system electrode positionable proximate a portion of the patient's cardiac conduction system;
- and
- a computing apparatus comprising processing circuitry, the computing apparatus operably coupled to the plurality of implantable electrodes, wherein the computing apparatus is configured to:
- determine a paced AV delay for use in delivery of cardiac conduction system pacing therapy using the cardiac conduction system electrode, wherein the paced AV delay is a time period between an atrial event and delivery of cardiac conduction system pacing therapy;
- determine a paced VV delay for use in delivery of cardiac conduction system pacing therapy using the cardiac conduction system electrode and delivery of left ventricular pacing therapy using the left ventricular electrode, wherein the paced VV delay is a time period between the delivery of the left ventricular pacing therapy and the delivery of the cardiac conduction system pacing therapy;
- and
- deliver either cardiac conduction system pacing therapy using the paced AV delay or cardiac conduction system pacing therapy and left ventricular pacing therapy using the paced AV delay and the paced VV delay.
A method comprising:
- determining a paced AV delay for use in delivery of cardiac conduction system pacing therapy using a cardiac conduction system electrode implanted proximate a portion of the patient's cardiac conduction system, wherein the paced AV delay is a time period between an atrial event and delivery of cardiac conduction system pacing therapy;
- determining a paced VV delay for use in delivery of cardiac conduction system pacing therapy using the cardiac conduction system electrode and delivery of left ventricular pacing therapy using a left ventricular electrode implanted proximate the patient's left ventricle, wherein the paced VV delay is a time period between the delivery of the left ventricular pacing therapy and the delivery of the cardiac conduction system pacing therapy;
- and
- delivering either cardiac conduction system pacing therapy using the paced AV delay or cardiac conduction system pacing therapy and left ventricular pacing therapy using the paced AV delay and the paced VV delay.
