Abstract
Systems and methods for pacing cardiac conductive tissue are described. A medical system includes an electrostimulation circuit that may generate His-bundle pacing (HBP) pulses for delivery at or near the His bundle. In response to the delivery of the HBP pulse, the system senses a near-field cardiac activity representative of excitation of a para-Hisian myocardial tissue, and a far-field cardiac activity representative of excitation of the His bundle and a ventricle. The system classifies a tissue response to HBP into one of a plurality of capture types based on the sensed near-field and far-field cardiac activities. The system includes a control circuit to adjust one or more stimulation parameters based on the classified capture type. The electrostimulation circuit generates and delivers the HBP pulses according to the adjusted stimulation parameters to excite the His bundle.
