Abstract
A system and method are provided for monitoring cardiac wall motion. A cardiac lead is provided with a motion sensor that is responsive to an excitation signal. The motion sensor signal induced by the excitation signal varies in time due to motion caused by myocardial wall motion. The time-varying motion sensor signal is obtained by sensing circuitry and provided to a processor for use in computing a wall motion parameter useful in assessing ventricular function. The processor provides wall motion parameter output for display or storage. Pacing parameters may be optimized according to wall motion parameter measurements obtained during iterative procedures using the lead-mounted motion sensor.
