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 ...
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 ...
