摘要
This disclosure relates to an active implantable medical device of the cardiac resynchronizer type. The device includes a pulse generator to produce pacing pulses, at least one detection electrode for detecting atrial and ventricular events, at least one stimulation electrode, a memory storing executable instructions, and a processor configured to execute the instructions. The processor is configured to execute the instructions to apply an atrioventricular delay (AVD) between a sensed or stimulated atrial event and the delivery of a ventricular pacing pulse, quantify a degree of fusion between the delivery of a pacing pulse to a cavity and a spontaneous contraction of another cavity, calculate a fusion rate, and modify the value of the AVD applied to the delivery of said ventricular pacing pulse, as a function of a comparison.
