测定心脏兴奋时所产生的磁场的记录称为心磁图(MCG)。近年来,对心赃的传导系统,特别是希氏—蒲肯野氏传导系统(HPS)的磁场的测定已引起广泛瞩目。 HPS兴奋所产生的磁场与通常心磁图相比是极其微小的。为消除干扰,需要高灵敏度的记录和解析,因此又称为高分辨力心磁图(HRMCG)。测量时,使用的是高精度的超导量子干涉元件SQUID,因此,又称为SQUID磁通计。 HRMCG的测定法和信号处理
The measurement of the magnetic field generated when the heart is excited is called the magnetocardiogram (MCG). In recent years, widespread attention has been drawn to the determination of the magnetic field of heartburn systems, in particular, the Hirschko-Bauken field conduction system (HPS). The magnetic field generated by HPS excitement is extremely small in comparison with normal magnetocardiography. To eliminate interference, the need for high-sensitivity recording and analysis, it is also known as high-resolution magnetocardiography (HRMCG). Measurement, the use of high-precision superconducting quantum interference element SQUID, therefore, also known as SQUID fluxmeter. HRMCG assay and signal processing
