We measured the electrical current generated by the heart using a multichannel superconducting quantum interference device (SQUID) system. We tried to develop the three dimensional magnetocardiography (MCG) using this system.Regional myocardial depolarization was visualized noninvasively by MCG. Myocardial ischemia was evaluated using newly developed iso-integral map on MCG. MCG mapping was useful for diagnosis of ischemic heart disease. Premature cardiac contractions and the developmental changes in PQ, QRS and QT intervals were investigated in the foetus. Arrhythmias were analyzed using magnetoanatomical mapping. Partial atrial standstill was successfully diagnosed. Volume unloading of the ventricle was evaluated.

我们使用多通道超导量子干涉装置(SQUID)系统测量了心脏产生的电流。我们尝试利用该系统开发三维心磁图(MCG)，利用该系统对局部心肌去极化进行无创可视化。采用新研制的心电地形图等积分图评价心肌缺血程度。心电地形图对缺血性心脏病的诊断有一定价值。观察胎儿期前收缩及PQ、QRS、QT间期的发育变化。应用磁解剖标测对心律失常进行分析。成功诊断出部分房性停搏。评估脑室容量卸载情况。
