The nuclear stethoscope: a simple device for generation of left ventricular volume curves

Am J Cardiol. 1976 Nov 23;38(6):747-50. doi: 10.1016/0002-9149(76)90352-0.

Abstract

Initial evaluation has begun of a system for displaying left ventricular time-activity curves, relating the intraventricular content of radioactivity with the cardiac cycle as determined by the patient's electrocardiogram. Major problems include proper positioning of the detector, correction for background radioactivity outside the ventricle and calibration of the device to permit conversion of measurement of radioactivity to measurement of ventricular volumes.
