ABSTRACT:
A method and apparatus for audibly reproducing a heartbeat at a user selected repetition rate by the steps of: detecting heart sound patterns and storing a representation of heart sound patterns having a duration that encompasses one heartbeat; analyzing the stored representation to determine the duration of one heartbeat; audibly and repeatedly reproducing a portion of the stored representation extending over a period equal to the duration of one heartbeat such that each repetition of the audibly reproduced portion extends over a time period substantially equal to the duration of one heartbeat; and selecting the repetition rate at which the portion of the stored representation is repetitively produced.
