description A meter for measuring the heart left ventricular ejection characteristic. The meter includes a circuit for emphasizing the left ventricular ejection phase preferentially to the other heart beat phases. According to a preferred embodiment, a circuit is provided which emphasizes signals of a blood volume waveform sensed by a pulsed light, source, photoelectric probe in a range of about 3.75 to 6.75 hertz.
