在心律失常与心电研究中,近年来心电标测技术越来越被重视且得到广泛应用,并成为研究心电生理与病理、心律失常的诊断与治疗以及心肌梗塞定位、面积测量的重要方法之一。心电标测从方法学上分为等电位标测(Isopotential Mapping)和等时标测(Isochronal Mapping)。前者是比较同一时间上的电位正负及其数值,由此确定心肌除极的方向。通常用于体表标测,适于研究心肌梗塞面积、范围和预激综合征(WPW);后者则是比较心肌除极先后顺序及其传导时间。通常用于心内、外膜及心肌标测,适于研究心律失常。从标测图型来分包括:P波标测(适宜研究窦房结和心房除极与传导);QRS波标测(心室肌的除极与传导);S—T段及T波的标测(主要用于研究心室复极)。等时标测通常用于P及QRS波标测。
In the study of arrhythmia and electrocardiogram, more and more attention has been paid to ECG detection technique in recent years, and it has become an important research in the diagnosis and treatment of cardiac electrophysiology and pathology, arrhythmia, myocardial infarction location and area measurement One of the ways. ECG mapping from the methodology is divided into Isopotential Mapping (Isopotential Mapping) and Isochronometry (Isochronal Mapping). The former is to compare the positive and negative potential and its value at the same time, thus determining the direction of myocardial depolarization. Usually used for surface mapping, suitable for studying myocardial infarct size, range and WPW; the latter is to compare the sequence of myocardial de-electrification and its conduction time. Commonly used in cardiac, epicardial and myocardial markers, suitable for studying arrhythmias. From the mapping pattern to include: P-wave mapping (suitable for the study of the sinus node and atrial depolarization and conduction); QRS wave mapping (ventricular depolarization and conduction); S-T segment and T wave standard Measured (mainly used to study ventricular repolarization). Isochronometric usually used for P and QRS wave mapping.
