Cardiac contractility modulation system pulse generator
Definition
A hermetically-sealed, battery-powered device implanted beneath the skin to produce electrical signals delivered to the heart via implantable cardiac pacing leads during the ventricular absolute refractory period (ARP) to enhance the strength of the heart [cardiac contractility modulation (CCM)], typically as treatment for heart failure. The device is programmed by and transmits cardiac diagnostic data to an external programmer telemetrically.
