The significant difference of magnetocardiogram between a healthy heart and the heart with right bundle branch block was observed.

实验结果表明，健康人与心脏病患者的心脏磁场信明差。

A high temperature superconducting quantum interference device (SQUID) was fabricated for magnetocardiogram (MCG) measurement, and a single-channel dc SQUID magnetocardiograph was developed.
