The Displacement Cardiograph

The displacement cardiograph (DCG) is a non-contacting electromagnetic instrument for the recording of heart movement. Its field penetrates deep into the body and is extremely sensitive thereby allowing the recording of myocardial movement from patients regardless of body shape or posture even by paramedical personnel. A summary of recordings from normal subjects, patients and animals is described here showing the DCG's flexibility as a diagnostic tool and as a device for basic physiological studies into the kinetics of organs.
