ABSTRACT:
A method of obtaining a continuous sequence of horizontal vectorcardiograms from an ambulatory patient throughout a 24-hour period. A simplified five-electrode ECG lead system is affixed to the patient and the ECG signals are recorded on a portable magnetic tape recorder attached to the patient. Thereafter, the tape is removed from the recorder and taken to a processing station for playback, display, and analysis. The tape is played back at high speed to permit rapid scanning of the tape for anomalies in the vectorcardiograph. Anomalies can then be studied in detail by playing back the tape at a reduced speed. The vectorcardiographs exhibit high correlation with those obtained by use of the more common, but more complex, Frank lead system.
