    摘要： The peak potential values of each cardioelectric wave components detected from the body surface are uniquely presented as a few iso-potential and isochronous contour maps by the electrocardiac peak mapping (EPM) method and apparatus described. The change in the size and the contour of the relevant EPM maps provides a simple, non-invasive, yet sensitive means for clinical diagnosis of at least the following heart diseases:1) the locations and sizes of myocardial infarction (hereafter, MI),2) primary and second cardiomyopathies,3) locations and sizes of "non-Q-wave MI", which can not be diagnosed by conventional electrocardiography, and4) various intracardiac conduction blocks and Wolff-Parkinson-White syndrome,5) various repolarization abnormalities and their quantitative analysis.The EPM apparatus comprises an elastic Waistcoat with embodied special electrodes, signal preprocessors, a multiplexer, a main differential amplifier, and a general purpose computer with appropriate software. The EPM analysis includes the identification of the peak potential and peak time displacement, the contruction of the isopotential and isochronous maps and the diagnosis of heart diseases. The diagnosis is achieved by comparison of the statistically obtained normal values to that of a patient. The complete EPM process can be carried out within ten minutes.

    摘要翻译： 从身体表面检测到的每个心电波分量的峰值电位值通过所述的心电图峰值映射（EPM）方法和装置被唯一地表示为几个等电位和等时线图。 相关EPM图的大小和轮廓的变化为至少以下心脏病的临床诊断提供了一种简单，非侵入性但敏感的方法：1）心肌梗塞的位置和大小（以下称为MI）， 2）原发性和第二型心肌病，3）不能通过常规心电图诊断的“非Q波MI”的位置和大小，以及4）各种心内传导阻滞和Wolff-Parkinson-White综合征，5）各种复极化 异常及其定量分析。 EPM装置包括具有实施的专用电极，信号预处理器，多路复用器，主差分放大器和具有适当软件的通用计算机的弹性Waistcoat。 EPM分析包括峰值电位和峰值时间位移的识别，等电位和等时图的构建以及心脏病的诊断。 通过将统计学上获得的正常值与患者的正常值进行比较来实现诊断。 完整的EPM过程可以在十分钟内完成。
