Abstract

Although measurement of magnetic fields has played an important role in physics and geology, until recently it has not been an important factor in clinical measurements. The reason for this is that the magnetic field produced by currents flowing in the human body is extremely small compared with the earth's magnetic field and the magnetic noise associated with urban backgrounds. The magnetic fields produced by currents flowing in the human heart are 106 smaller than the earth's magnetic field. With the development of superconducting SQUID magnetometers and superconducting circuitry capable of measuring a gradient of a very small magnetic signal in the presence of a large background magnetic field, it has become practical to record the magnetocardiogram of the human heart.
