Since ECG was invented in 1903, this is the first time in history that a full information multi-band and multi-linear electrophysiological cardiogram has been used to successfully scan and record on the human body surface. Since it is able to record various multi-band, multi-track linear electric signals of cardiac electrophysiological activities that correspond to different regions of the entire heart, it has thus been denominated as "electrophysiocardiogram" (EPCG). A traditional ECG is always represented by a characteristic wave form, which resembles a string. For a long period of time, ECG has had a lot of mysteries surrounding it, it maybe because ECG has a lot of mixed signals buried in such convolutionary forms, which limits the amount of the signals that are discernable and determinable. For the first time, the EPCG technology has allowed cardiac signals to be convoluted into the linear wave form, which is then processed through various new approaches featuring multiple frequency bands, multiple dimensions and multiple patterns, and consequentially recorded as the following types of signals within the ranges of P wave and T wave: multiple frequency band signals, signals of different regions and different locations, forward waves and negative waves. Therefore, EPCG may help to solve many puzzling scientific questions regarding heart, such as exactly how many electric signals are involved in heart excitation, pacing, conduction and action, as well as many other intriguing questions about heart, and thus would become a very helpful tool in clinical practice.
自1903年心电图(ECG)发明以来,这是历史上首次使用全信息多波段多线性电生理心动图在人体体表成功进行扫描和记录。由于它能够记录与整个心脏不同区域相对应的各种心脏电生理活动的多波段、多轨迹线性电信号,因此被命名为“电生理心动图”(EPCG)。传统的心电图总是由一种类似线条的特征波形表示。长期以来,心电图一直笼罩着许多谜团,这可能是因为心电图中有许多混合信号以这种卷积形式存在,这限制了可分辨和可确定的信号量。电生理心动图技术首次使心脏信号被卷积成线性波形,然后通过具有多频段、多维度和多种模式的各种新方法进行处理,并相应地记录为P波和T波范围内的以下几种信号类型:多频段信号、不同区域和不同位置的信号、正向波和负向波。因此,电生理心动图可能有助于解决许多关于心脏的令人困惑的科学问题,例如心脏兴奋、起搏、传导和活动究竟涉及多少电信号,以及许多其他关于心脏的有趣问题,从而成为临床实践中非常有用的工具。
