Abstract
Systems and methods for pacing cardiac conductive tissue are described. In an embodiment, a medical system includes an electrostimulation circuit to generate His-bundle pacing (HBP) pulses. A sensing circuit senses an atrial activation. A control circuit detects a retrograde atrial conduction timing, such as a His-to-atrial interval between the HBP pulse and the sensed atrial activation in response to the HBP pulse, and verifies capture status using the determined retrograded atrial conduction timing. Based on the capture status, the control circuit determines a HBP threshold, and the electrostimulation circuit delivers HBP pulses in accordance with the determined HBP threshold.
