From: A vector-free ECG interpretation with P, QRS & T waves as unbalanced transitions between stable configurations of the heart electric field during P-R, S-T & T-P segments

Figure 3

High resolution (1 KHz sampling rate) triaxial ECG was recorded on a healthy 50 years old male from FigureĀ 1. Showing recorded voltages in the horizontal (X-Z) plane. Electric field moves during the cycle: before QRS, in PR it is retrosternal, after QRS it moves dorsally and to the right. T-wave brings it back to the left in TP1 and diastolic feeling moves it back to the retrosternal position in TP3.
