Abstract:
1. A system for heart performance characterization and abnormality detection, comprising: an interface conditioned for receiving an electrical signal indicating heart electrical activity of a patient over a heart beat cycle, said electrical signal being acquired at a particular anatomical location; a gating signal generator conditioned for generating a gating signal to identifying a particular portion within said heart beat cycle, wherein the heart beat cycle comprises more than one individual phase, and the particular portion is one of the phases of the heart beat cycle; an acquisition device, responsive to said gating signal, conditioned for deriving from the received electrical signal, first and second voltage potentials, a computation processor conditioned for deriving a dynamic impedance representative value by adjusting a baseline impedance value by a ratio of the first and second voltage potentials, said dynamic impedance configured to represent an average impedance at said particular anatomical location over a time period comprising said particular portion within said heart beat cycle.
