Abstract:
1. A therapeutic stimulation system comprising: an implantable cardiac stimulation device comprising: an implantable stimulation generator; at least one implantable lead adapted for connection to the implantable stimulation generator and further adapted for at least one of sensing physiologic activity and delivery of therapy; memory; and a controller in communication with the memory and with the at least one implantable lead and stimulation generator and configured to automatically evaluate a patient's physiologic status and selectively induce delivery of therapeutic stimulation under variable timing parameters; and an external measurement system comprising an ultrasonic imager adapted to measure at least one of strain and velocity of myocardial tissue and wherein the system is adapted to evaluate the at least one of strain and velocity measures and adjust the variable timing parameters of the implantable stimulation device to increase synchrony of the at least one of strain and velocity of myocardial tissue.
