Classification: CPC A | IPC A

Claim 0:
1. A system for pacing a heart of a patient, comprising:
an electrostimulation circuit configured to provide electrostimulation energy to an interventricular septum between left and right ventricles of the heart;
a cardiac event detector configured to:
receive physiological information of the patient including an atrial activity and a physiologic signal sensed at or near a His-bundle region;
determine a sensing window following the atrial activity, the sensing window shorter than a programmed atrial-to-ventricular delay (AVD) and longer than a patient-specific intrinsic atrial-to-His bundle interval (AHI); and
determine a presence or an absence of a conduction system activity at or near a His-bundle region using the sensed physiologic signal in the sensing window; and
a control circuit configured to generate a control signal to the electrostimulation circuit to initiate electrostimulation of the interventricular septum in response to the absence of the conduction system activity in the sensing window, and to withhold the electrostimulation of the interventricular septum in response to the presence of the conduction system activity in the sensing window.
