The heart detective described is a portable device for detecting and indicating when heart sounds emanating directly from a physical area under auscultation are representative of a heart disorder. The device detects the audio sounds emanating from the classical four physical areas of auscultation and compares these detected sounds to prerecorded sounds of the same areas representing a known heart disorder. A comparison is made between the detected sounds and the prerecorded sounds, and the correlations are indicated in a display on the device so that a determination may be made if the heart disorder is present. The device also contains means for accepting an auxiliary transducer for detecting heartbeat pulses and indicating the pulse rate.
