In a “normal” electrocardiogram (ECG), the transition of the QRS axis in the precordial leads occurs between leads V 3 and V 4 (i.e., there is a dominant S in V 3 and a dominant R in V 4).

The ECG shows an irregularly irregular rapid ventricular rate, approximately 120 beats per minute, with no visible P waves. The frontal plane QRS axis is –30° and the R wave voltage in AVL is 15 mV.
