Abstract

Electrical activity can be localized by magnetocardiography (MCG) non-invasively. In this study a 37-SQUID (Super Conducting Quantum Interference Device) sensor multi-channel system (KRENIKON) was used to assess the potential of magnetocardiography to localize accessory pathways with a multichannel system. Seven WPW patients were studied by means of magnetocardiography. Prior to the MCG recordings, the site of the accessory pathway had been determined in all patients by invasive catheter mapping. MR images of the heart were used for anatomical correlation. The magnetocardiographic localization of the accessory pathway corresponded with catheter mapping within 2.1 cm on average (total range: 0-5 cm). This is thus, a promising new method for non-invasive localization of accessory pathways in WPW patients.

摘要

心脏电活动可通过心磁图（MCG）进行无创定位。在本研究中，使用了一个37通道超导量子干涉装置（SQUID）传感器多通道系统（KRENIKON），通过多通道系统评估心磁图定位旁路通道的潜力。对7例预激综合征（WPW）患者进行了心磁图研究。在心磁图记录之前，所有患者均通过有创导管标测确定了旁路通道的位置。心脏的磁共振成像用于解剖学对照。旁路通道的心磁图定位与导管标测平均相差2.1厘米（范围：0 - 5厘米）。因此，这是一种在WPW患者中无创定位旁路通道的有前景的新方法。
