label: Abnormal ventricular axis
label_lc: abnormal ventricular axis
description: "Any deviation from the normal direction of the ventricular axis. The left ventricle makes up most of the heart muscle under normal circumstances and therefore generates the most electrical force visible on the EKG. The normal ventricular axis is directed downward and slightly towards the left. The ventricular axis can be determined by analyzing the QRS complex, which represents ventricular depolarization."
