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，健康人与心脏病心脏磁场信号存在明差异。

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

研制了用于心磁直流高温子干涉器,并建立了单通道高温直流超导子干涉器心磁图仪。
