The axis of the ECG is the major direction of the overall electrical activity of the heart. It can be normal, leftward (left axis deviation, or LAD), rightward (right axis deviation, or RAD) or ...

Left axis deviation occurs when the QRS axis falls between -30 and -90. There are a variety of causes, including left anterior fascicular block and left ventricular hypertrophy. See the ECG basics ...

Question 3 Left axis deviation. Explanation. There are three ways to work out the axis from an ECG: 1. Read the ECG print out. The ECG interpretive software is usually very accurate at working out the ...

The QRS complex is positive in lead I and negative in lead II and also negative in lead aVF – indicating left axis deviation TIP When you see RBBB ... Which of the following is true? A The ECG is ...

ECG interpretation in athletes requires careful analysis to properly distinguish physiological changes related to athlete's heart from findings suggestive of an underlying pathological cardiac ...

Clockwise rotation was associated with higher rates of other mild ECG abnormalities, including axis deviation, ST depression, atrial fibrillation, T wave inversion, and minor Q waves. Cox analysis ...

Methods The study populations included 200 patients with HCM and 563 athletes grouped as follows: ‘group 1’, including normal ECG and isolated increase of QRS voltages, which are considered ...
