Detection Of Back Magneto-Cardiogram For Heart Disease Using Pico-Tesla Resolution Amorphous Wire Magneto-Impedance Sensor

We measured the magneto-cardiogram at the back of the human body (Back Magneto-cardiogram; Back-MCG) using the pico-Tesla resolution amorphous wire magneto impedance sensor (PT-MI sensor) and found that the double-peak magnetic field waveform appeared in the healthy subject's Back-MCG only, while disappeared in the angina pectoris patient's Back-MCG. We also found that the double-peak waveform appeared for a while such as around 1 hour even in the Back-MCG of the angina pectoris patients after application of an ELF magnetic stimulus with stroking a magnetized crashed stone packed pipe on the body through 10 min.
