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 ...

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 always look for 1 st degree heart block and/or left ...

A left anterior fascicular block, also known as left anterior hemiblock, occurs when the anterior fascicle of the left bundle branch is no longer able to conduct action potentials. The criteria to ...

There is clearly a broad QRS complex which is predominantly positive in V1 indicative of RBBB. You can also see an RSR pattern to the QRS complex in V1 reflective of the fact that the left ventricle ...

Background In athletes, ECG changes from physiological cardiac remodelling are common but can overlap with findings from a pathological disorder. We compared ECG findings in a group of elite high ...
