1. A plural-external-anatomical site vector method for monitoring, exclusively externally, a subject'"'"'s hemodynamic condition utilizing, and based upon, exclusively externally collected data relating to murmur and heart sound phenomena, detected by, and collected exclusive from, plural, externally anatomically-attached, stably positioned, three-orthogonal-axis accelerometers, said method comprisingattaching at least a pair of three-orthogonal-axis accelerometers in stable, spaced positions externally to a subject'"'"'s anatomy,during at least one cardiac cycle of the subject, collecting signal data collaboratively from the so-attached, plural accelerometers,processing such collaboratively collected data to obtain vector magnitude and directionality information associated, respectively, with the least two accelerometers, andanalyzing such collaboratively collected and processed vector magnitude and directionality information for assessment of the subject'"'"'s hemodynamic condition.
