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 ...

Question 1. What abnormalities are present on this ECG? A There is LBBB B There is RBBB and second degree heart block C There is RBBB D There is RBBB, first degree heart block and left axis deviation ...

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.

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 ...
