Sažetak
An implantable system having a left ventricular pacing lead for implantation in the great cardiac vein via the coronary sinus of a patient's heart. The pacing lead includes a sensor for measuring the velocity of blood flowing through the coronary sinus. An implantable medical device (IMD) coupled to the pacing lead monitors the blood flow signal from the sensor and delivers pacing pulses to the patient's heart as a function of the blood flow signal. The IMD integrates the blood flow signal to estimate blood flow volume and adjusts a pacing parameter of the pacing pulses to maximize the blood flow. In a multi-chamber pacing system, the IMD continuously adjusts the atrial and ventricular (AV) delay in order to maximize the integral of the velocity signal received from pacing lead. In a multisite pacing system, where the IMD includes a plurality of ventricular pacing leads, the IMD adjusts the interventricular delay.
