Classification: CPC A | IPC A

Claim 12:
13. A method, comprising:
sensing a first cardiac electrical signal by a sensing circuit;
receiving one or more cardiac electrical signals comprising the first cardiac electrical signal;
determining at least one feature of the first cardiac electrical signal;
comparing the at least one feature to left bundle branch signal criteria;
determining a left bundle branch signal in response to the feature meeting the left bundle branch signal criteria;
generating 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;
generating pacing pulses for delivery by the pacing electrode in the left portion of the ventricular septum; and
determining 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.
