A stethoscope-mounted cardiac synchronizer

As an aid to the diagnosis of cardiac function, a compact circuit was designed to attach to the head of a physician's stethoscope and detect electrocardiogram R and T waves, indicating each by the brief flashing of an L D. With feedback on electrical activity in the heart in parallel with acoustical feedback, a physician will have greater ability to diagnose normal and diseased operation of the heart. The circuit was prototyped using a custom multilayered board and surface mount components. More advanced versions are now being considered in the forms of a full custom Integrated circuit and a PIC microcontroller.
