A Study of Mean Electrical Axis (QRS
... Electrocardiogram is a recording of electrical potential difference at two points of heart during cardic cycle. This current flows (depolarisation wave) from base to apex of heart and thus throughout depolarisation phase apex of heart remains positive in respect to the base. Average direction of thi ...
