Electrocardiograms by telemetry.
Radiocardiography makes it possible to transmit an electrocardiogram by air from patient to recording device. The distance of transmission may be a few feet, as in a physician's office; or it may be many miles, as when transmitting electrocardiograms from aircraft, rockets or satellites to the earth. The radiocardiographic method has the advantage of versatility, simplicity, freedom of movement for the patient and high amplitude, and is especially suited for recording electrocardiograms during exercise.
