Abstract
In some examples, a method comprises sensing one or more left-ventricular activations via one or more electrodes of a left-ventricular lead, wherein each of the one or more left-ventricular activations are in response to delivery of an electrical stimulation to a heart of a patient; determining one or more left-ventricular activation metrics based on the sensed one or more left-ventricular activations; and determining whether the electrical stimulation provided conduction system pacing based on the one or more ventricular activation metrics.
Claims20
A method comprising:
- sensing, by a medical device, two or more left-ventricular activations via two or more electrodes of a plurality of electrodes of a first lead, the first lead comprising a left-ventricular lead, wherein the two or more left-ventricular activations are in response to delivery of one or more electrical stimulations to a heart of a patient by a second lead different from the first lead;
- determining, by the medical device, one or more left-ventricular activation metrics based on the sensed two or more left-ventricular activations, wherein determining the one or more left-ventricular activation metrics comprises comparing the two or more left-ventricular activations to each other;
- determining, by the medical device, that the one or more electrical stimulations did not provide conduction system pacing (CSP) based on the one or more left-ventricular activation metrics;
- and
- in response to determining that the one or more electrical stimulations did not provide CSP, adjusting a position of an electrode used to deliver the one or more electrical stimulations.
