• 摘要：

• 心磁图是一种高精度、无创、无接触的心脏电活动磁场信号检测分析技术。相较于传统心电图，心磁图具有更高的时间分辨率和空间分辨率，且不受人体组织传导不均性的干扰，能更直接地反映心肌细胞的真实电活动。近年来，随着检测技术和信号分析方法 的进步，心磁图在心律失常的机制研究、临床诊断、病灶定位、疗效和预后评估以及胎儿心律失常筛查中展现出独特价值。本文系统综述了心磁图的物理原理与检查方法 ，重点阐述了其在心律失常中的最新应用进展。同时，分析了心磁图当前面临的技术挑战与临床局限性，并对其未来的发展方向进行了展望。

• Magnetocardiography is a high-precision, non-invasive, non-contact detection and analysis technique for magnetic field signals of cardiac electrical activity. Compared with conventional electrocardiography, magnetocardiography has higher temporal and spatial resolution and is not interfered by heterogeneous conduction of human tissues, which can more directly reflect the real electrical activity of cardiomyocytes. In recent years, with the advancement of detection technology and signal analysis methods, magnetocardiography has shown unique value in the mechanistic research, clinical diagnosis, lesion localization, evaluation of therapeutic effect and prognosis of arrhythmias, as well as screening for fetal arrhythmias. This article systematically reviews the physical principles and examination methods of magnetocardiography, focuses on its latest application progress in arrhythmias. Meanwhile, it analyzes the current technical challenges and clinical limitations of magnetocardiography, and prospects its future development directions.
