Implantable cardiac stimulator, system, device and method for monitoring cardiac synchrony
First Claim
1. 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 from 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 movement of said cardiac wall movements at said second location at a second lateral distance from 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.

Abstract
In a system and method for monitoring cardiac synchrony in a human heart, a first sensor is positioned at a first cardiac wall location of a heart that is subject to movements related to longitudinal valve plane movements along the longitudinal axis of the heart, and the first sensor measures said cardiac wall movements at the first cardiac wall location and emits a first sensor output signal corresponding thereto, a second sensor is positioned at a second cardiac wall location of the heart that is subject to movements related to longitudinal valve plane movements along the longitudinal axis of the heart, and the second sensor measures the cardiac wall movements at the second cardiac wall location and emits a second sensor output signal corresponding thereto. A lead arrangement is electrically connected to the first and second sensors and conducts the first and second sensor output signals therefrom to processing circuitry that processes the first and second sensor output signals to produce a synchronization signal therefrom indicative of synchrony in the respective valve plane movements at the first and second cardiac wall locations.
