Ventricular conduction system pacing therapy control

A method comprising:

• sensing at least one cardiac electrical signal;
• generating first pacing pulses for delivery to a first combination of ventricular pacing sites comprising at least a first ventricular conduction system pacing site and a second ventricular pacing site;
• and
• withholding delivery of the first pacing pulses from the second ventricular pacing site for at least one ventricular cycle while delivering the first pacing pulses to the first ventricular conduction system pacing site for the at least one cardiac cycle;
• determining a normal ventricular conduction condition from the at least one cardiac electrical signal sensed during the at least one cardiac cycle;
• and
• in response to detecting the normal ventricular conduction condition, generating second pacing pulses for delivery to the first conduction system pacing site without delivering the second pacing pulses to the second ventricular pacing site.

A non-transitory, computer-readable medium storing a set of instructions which, when executed by control circuitry of a medical device system, cause the medical device system to:

• sense at least one cardiac electrical signal;
• generate first pacing pulses for delivery to a first combination of ventricular pacing sites comprising at least a first ventricular conduction system pacing site and a second ventricular pacing site;
• and
• withhold delivery of the first pacing pulses from the second ventricular pacing site for at least one ventricular cycle while delivering the first pacing pulses to the first ventricular conduction system pacing site for the at least one cardiac cycle;
• determine a normal ventricular conduction condition from the at least one cardiac electrical signal sensed during the at least one cardiac cycle;
• and
• in response to detecting the normal ventricular conduction condition, generate second pacing pulses for delivery to the first conduction system pacing site without delivering the second pacing pulses to the second ventricular pacing site.
