Abstract
A vector method for monitoring a subject's hemodynamic condition including (a) utilizing at least one, external or internal, anatomy-attached, three-axis accelerometer, collecting from the subject, during a selected cardiac cycle, related, three-orthogonal-axes accelerometer signal data, (b) following such collecting, processing collected signal data to obtain associated, signal vector, magnitude and directionality information, and (c) analyzing such obtained vector information for assessment of the subject's heart hemodynamic condition. ECG and signal time-frequency data is also collected and used in certain manners and implementations of the invention.
