WebECG> Basics. In brief, you need to understand and remember: the depolarization and repolarization sequence in the heart. the fact that when a wavefront of depolarization travels towards the + electrode and away from the electrode attached to the - terminal, a positive-going deflection will result. the voltage recorded along a particular lead ... Web1 de jan. de 2006 · The approximate location of the mean electrical axis can be found by identifying the lead with the tallest R wave. The mean electrical axis will be within 30 degrees of the positive pole of this lead. In this ECG, lead II has the tallest R wave, indicating that the mean electrical axis is normal. 4.
