Abstract:
1. An apparatus comprising: a timing circuit configured to receive a specified A-H delay, for use for specifying timing between a paced or sensed atrial contraction time (A) and a His-bundle pacing time (H), the specified A-H delay computed using a measured cardiovascular physiologic parameter including at least one of a P-wave duration of an electrical cardiac signal, a parameter of a heart sound signal obtained using a heart sound sensor and indicative of mechanical vibrations of a heart, or a left atrial pressure parameter; and an electrostimulation energy delivery control circuit configured to be communicatively coupled to the timing circuit and to provide a control signal, in response to a paced or sensed atrial contraction, and using the specified A-H delay, to trigger delivery of an electrostimulation at a location that is at or near the His-bundle.
