1. Apparatus for transtelephonic monitoring of heart valve sounds comprising: a sensor for sensing heart valve sounds and for converting the heart valve sounds to an input signal; means responsively coupled to said sensor for windowing acoustic events in the input signal and for converting each acoustic event to a respective digital signal; means responsively coupled to said converting means for storing said digital signals; means responsively coupled to said storing means for transmitting said digital signals transtelephonically; means responsively coupled to said transmitting means for receiving said digital signals transtelephonically; and means responsively coupled to said sensing means and said storing means for timetagging each distal signal whereby said transmitting means may transmit each digital signal over an arbitrary time relative to the time required to said sensor to convert said physiological signal to said input signal and relative to other digital signals.
