Electrode positions on an ECG (EKG). When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative. If it is at 90 degrees then the complex is ‘isoelectric’ i.e. the R and S wave are the same size.

WebbTall R Wave in V1: The Four Categories. Let’s take a logical approach to the meaning of a tall R wave in V1. First, understand that V1 is the only right-sided lead in the standard 12-lead ECG, and therefore, a tall R wave in V1 represents increased net rightward depolarization. Second, remember that the causes of increased right-sided ... WebbECG criteria for early repolarization. According to MacFarlane et al: Notch or slur in transition between R-wave and ST segment.
