Scintillation probe detector in the assessment of cardiovascular disease

A simple device that permits measurement of cardiac function in humans after intravenous injection of technetium-99m-labeled albumin or red blood cells is described. The device (nuclear stethoscope cardiac probe) is based on the application of microprocessor technology to a scintillation detector. It can be used to monitor ventricular function continuously and in exercise testing for the detection of coronary heart disease.
