心电图学教程Electrocardiogram teaching course;目 录;第一部分 临床心电图教程Clinical electrocardiographyteaching course;（三）正常心电图波形normal electrocardiographic complexes;正常心电图波形normal electrocardiographic complexes; 通常可根据肢体Ⅰ、 Ⅲ导联QRS波群的主波方向，以估测心电轴的大致方位： 若Ⅰ、Ⅲ导联QRS波的主波均为正向波，则可推断为正常心电轴（0?～90?）；; 若Ⅰ导联出现较深的负向波，则属心电轴右偏； ; 若Ⅲ导联出现较深的负向波，则属心电轴左（上）偏。此处，还可改变取其他二个互相直交的导联，例如Ⅰ导联与aVF导联以判定之，其结果大致相仿，但并不完全相同。;（二）正常心电图normal ECG;心电图综合波、间期和段的检测determination of ECG complexes, intervals, and segments;心率的检测determination of the heart rate;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;QRS波群;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;正常心电图综合波、间期和段的图解diagram of ECG complexes, intervals, and segments;（三）心房与心室肥大atrial and ventricular hypertrophy;1. 心房肥大atrial hypertrophy 2. 心室肥大 ventricular hypertrophy ;1. 心房肥大 atrial hypertrophy;①左心房肥大 left atrial hypertrophy ②右心房肥大 right atrial hypertrophy ③双心房肥大 biatrial hypertrophy ;左心房肥大 left atrial hypertrophy;右心房肥大 right atrial hypertrophy;双侧心房肥大 biatrial hypertrophy;2. 心室肥大 ventricular hypertrophy;左心室肥大 left ventricular hypertrophy;左心室肥大 left ventricular hypertrophy;左心室肥大 left ventricular hypertrophy;左心室肥大 left ventricular hypertrophy;右心室肥大 right ventricular hypertrophy;右心室肥大 right ventricular hypertrophy;右心室肥大 right ventricular hypertrophy;右心室肥大 right ventricular hypertrophy;双侧心室肥大 biventricular hypertrophy;（四）心律失常cardiac arrthythmias;（四）心律失常cardiac arrthythm
