The cardiac axis can be approximated by evaluating the combinations of the QRS complex polarities in leads I and aVF. [14] Positive in both leads I and aVF: normal axis (0° to 90°) Positive in lead I and negative in aVF: left axis deviation (-90° to -30°) or normal axis (...
both I and aVF +ve = normal axis both I and aVF -ve = axis in the Northwest Territory lead I -ve and aVF +ve = right axis deviation lead I +ve and aVF -ve lead II +ve = normal axis lead II -ve = left axis deviation...
Positive in both leads I and aVF: normal axis (0° to 90°) Positive in lead I and negative in aVF: left axis deviation (-90° to -30°) or normal axis (-30° to 0°) Negative in lead I and positive in aVF: right axis deviation (90° to 180°) Negative in both leads I ...
The QRS complex duration is normal (0.08 sec). The QT/QTc intervals are normal (300/410 msec). However, the QRS complex has anabnormal morphology.The axis is right ward,between +90° and+180° (negative QRS complex...
Normal axis: Net positive QRS complex in leads I and II. Right axis deviation: Net negative QRS complex in lead I but positive in lead II. Left axis deviation: Net positive QRS complex in lead I but negative in lead II. Extreme axis deviation (–90°to 180°): Net negative QRS comple...

Evidence of heart positioning issueswhile looking for an electrical axis deviation. Various other heart dysfunctionscan be diagnosed by a cardiologist based on ECG results. What does an electrocardiogram not show? ECGs records a normal sinus rhythm for the following heart issues and followup tests ar...
心电轴的检测 determination of axis deviation 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: 判断方法 Ⅰ导联 Ⅱ导联 Ⅲ导联 正常心电轴 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); 心电轴右偏 若Ⅰ导联出现较深的负向波,则属心电轴右偏; 心电轴左...
