Study of P-R Segment Using Magnetocardiographic Measurement

Magnetocardiographic measurement and analysis of P-R segments were studied using a SQUID fluxmeter in a PTB high performance magnetically shielded room. It was found that auricle depolarization and repolarization processes could be clearly distinguished by the difference in polarity on the equivalent magnetic field distribution, and the equivalent potential difference distribution maps. This confirmed that performing analysis of PR segments makes a valuable contribution to research on cardiomagnetism.
