C)Counterclockwise rotation.
D)Normal R wave progression.

Question

Quizplus · Accepted Answer

Counterclockwise rotation is when the transition zone is between V1 and V2 instead of the normal location in V3. This can be seen on the EKG as a counterclockwise loop in the precordial leads. Malrotation is a different abnormality where the heart is rotated on its axis, causing abnormal lead placement and inconsistent waveforms. Clockwise rotation is not a recognized term in EKG interpretation. Normal R wave progression refers to the expected increase in R wave amplitude from V1 to V6, which can be altered in some cardiac abnormalities.
