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

Claim 0:
1. A medical device system, comprising:
a sensing circuit configured to sense a first cardiac electrical signal;
a processor configured to:
receive one or more cardiac electrical signals including at least the first cardiac electrical signal;
determine at least one feature of the first cardiac electrical signal;
compare the at least one feature to left bundle branch signal criteria; and
determine a left bundle branch signal in response to the at least one feature meeting the left bundle branch signal criteria; and

a display unit configured to generate a user feedback signal comprising at least one of an audible progress indicator or a visual progress indicator for indicating advancement of a pacing electrode into a left portion of a ventricular septum, the display unit configured to adjust the user feedback signal in response to the processor determining the left bundle branch signal; and
a pulse generator configured to generate pacing pulses for delivery via the pacing electrode in the left portion of the ventricular septum; and
wherein the processor is further configured to 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 first 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.
