A CdTe Ambulatory Ventricular Function Monitor

A prototype device consisting of two arrays of CdTe detectors, ECG amplifiers and gate, microprocessor and tape recorder was devised to record simultaneous ECG and radio-nuclide blood pool data from the left ventricle for extended periods during normal activity. The device is intended to record information concerning both normal and abnormal physiology of the heart and to permit the evaluation of new pharmeceuticals under everyday conditions. Preliminary results indicate that the device is capable of recording and reading out data from both phantoms and patients.
