ABSTRACT:
This document discusses cardiac rhythm management systems and methods using the MVC-to-AE time between mitral valve closure (“MVC”) and aortic ejection (“AE”) of the same heart contraction, sometimes referred to as the isovolumic contraction time (“ICVT”). In one example, the MVC-to-AE time is used for predicting which patients will respond to cardiac resynchronization therapy (CRT), or other therapy. In another example, the MVC-to-AE time is used as a wellness indicator. In a further example, the MVC-to-AE time is used to select or control a therapy or therapy parameter. In one example, the MVC and AE are obtained using an accelerometer signal, however, plethysmography, tonometry, or other techniques may alternatively be used.
