心电图(ECG)中的QRS波群代表左、右心室肌除极的电位变化,在人的成长过程中可因生理因素和病理因素发生振幅和时限的改变,QRS波振幅和时限异常是临床上诊断心脏疾病的常用指标。准确分析QRS波群所包含的信息和掌握其规律,在医学诊断中具有重要价值。因此,不同地域、民族及性别的健康人群ECG中QRS波振幅变化的研究就显得非常必要。以往关于QRS波的研究较多,但以藏区较高地区人群为研究对象尚少见报道。本文采集的几组心电图QRS波振幅资料,旨在
The QRS complex in the electrocardiogram (ECG) represents the potential changes in the depolarization of the left and right ventricular muscles. Changes in amplitude and duration may occur due to physiological and pathological factors during human growth. The amplitude and time-of-instability of the QRS wave are clinically Diagnostic heart disease commonly used indicators. Accurate analysis of the information contained in the QRS complex and its rules, in the medical diagnosis of great value. Therefore, it is necessary to study the change of QRS wave amplitude in the ECG of healthy people of different regions, ethnicities and genders. In the past, there were many studies on QRS wave, but it was seldom reported in the population of higher Tibetan areas. This collection of several sets of ECG QRS amplitude data, intended
