title: Electronic trace of the mean axis of the heart.
abstract: A technique is described for tracing the mean electrical axis of the heart from an ECG waveform generator on a general purpose CRT, which could be used to teach medical students and might also be useful as an auxillary unit to investigate the possible applications of the mean electrical axis to the diagnosis of cardiac disorders.
