Patent ID: 8219194

Claim:
A system for monitoring cardiac synchrony in a human heart, said system comprising: a first sensor configured for positioning at a first location laterally relative to a cardiac wall of a heart that is subject to movements related to longitudinal valve plane movements of said cardiac wall along the longitudinal axis of the heart, said first sensor being configured to measure said cardiac wall movements at said first location at a first lateral distance in relation to said cardiac wall and to emit a first sensor output signal corresponding thereto; a second sensor configured for positioning at a second location laterally relative to said cardiac wall of the heart that is subject to movements related to longitudinal valve plane movements along the longitudinal axis of the heart, said second sensor being configured to measure said cardiac wall movements at said second location at a second lateral distance relative to said cardiac wall, that is different from said first lateral distance, and to emit a second sensor output signal corresponding thereto; a lead arrangement electrically connected to said first and second sensors that conducts said first and second sensor output signals therefrom, respectively; and processing circuitry connected to said lead arrangement to receive said first and second sensor output signals therefrom, said processing circuitry being configured to process said first and second sensor output signals to produce a synchronization signal therefrom indicative of synchrony in the respective valve plane movements at said first and second cardiac wall locations.
