Abstract:
An implantable medical device system comprising:a flow sensor for measuring blood flowing through a coronary sinus of a patient's heart; a blood flow signal generated by the flow sensor; and an implantable medical device (IMD) coupled to the flow sensor, wherein the IMD is configured to output pacing pulses as a function of the blood flow signal; and an atrial and a ventricular pacing lead coupled to the IMD to deliver the pacing pulses to the patient's heart, wherein the IMD generates the pacing pulses as a function of the blood flow signal; wherein an AV delay of the pacing pulses is adjusted by the IMD as a function of the blood flow signal; wherein the IMD is configured to adjust the AV delay to increase a duration of blood flow through the coronary sinus.
