CLOSED-LOOP RESYNCHRONIZATION THERAPY FOR MECHANICAL DYSSYNCHRONY
摘要
An apparatus comprises a first impedance sensing circuit, a second sensing circuit, and an impedance-based cardiac dyssynchrony detector. The impedance sensing circuit senses an intracardiac local impedance signal that is indicative of a cardiac local wall motion of a first cardiac region from an implantable first bipolar pair of impedance sensing electrodes. The second sensing circuit is configured to produce a second sensor signal indicative of cardiovascular activity. The impedance-based cardiac dyssynchrony detector is configured for detecting cardiac dyssynchrony using a relationship between the first intracardiac local impedance signal and the second sensor signal. Other apparatuses and methods are disclosed.
