Patent ID: 11911166
Assignee: MEDTRONIC, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 25:
26. A non-transitory computer readable medium storing instructions which, when executed by a processor of a medical device system, cause the medical device system to:
sense a cardiac electrical signal by a sensing circuit of the medical device system;
determine at least one feature of the cardiac electrical signal;
compare the at least one feature to left bundle branch signal criteria;
determine a left bundle branch signal in response to the at least one feature meeting the left bundle branch signal criteria;
generate a user feedback signal comprising at least one of an audible progress indicator or a visual progress indicator that is adjusted in response to determining the left bundle branch signal for indicating advancement of a pacing electrode into a left portion of a ventricular septum;
generate pacing pulses delivered via the pacing electrode;
determine the at least one feature from the first cardiac electrical signal following delivery of a pacing pulse via the pacing electrode by:
detecting a pacing evoked response signal from the cardiac electrical signal; and
determining the at least one feature by determining an activation time interval from the delivered pacing pulse to the pacing evoked response signal; and

generate pacing pulses for delivery by the pacing electrode in the left portion of the ventricular system.
