When the transition zone is identified between leads V1 and V2, it indicates the presence of counterclockwise rotation in the heart's electrical activity. This phenomenon typically occurs when the electrical vector in the heart directs upward and towards the left, resulting in a pattern seen in the EKG rhythm. In this context, leads V1 and V2, located in the right precordial area, will display a shift in their electrical activity, which is characterized by a more pronounced R wave in V2 compared to V1.

In contrast, clockwise rotation would generally indicate that the transition zone occurs later, typically between V2 and V3, where there might be a dominance of R waves in both leads but little progression. Malrotation refers to an abnormal rotational pattern in the heart's electrical activity that does not align with conventional patterns, leading to difficulties in interpreting results. Normal R wave progression signifies a typical development of R wave amplitude from V1 through V6.

Thus, recognizing the transition zone between V1 and V2 as indicative of counterclockwise rotation is essential for the accurate interpretation of EKG patterns and for identifying underlying cardiac conditions.
