WebTall 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 ... WebThe inverted (negative) T-wave. T-wave inversion means that the T-wave is negative.
