Reverse progression of R wave - tall R wave in V1, tallest in V1 or V2 - is usually seen in right ventricular hypertrophy.

右心室肥厚时，R波反向发展，V1高R波，V2或V1最高。

For example, in left ventricular hypertrophy the axis is skewed further left; while right ventricular hypertrophy results in a deviation to the right.

例如，左心室肥厚时，心电轴进一步向左倾斜；而右心室肥厚导致向右偏移。

Finally because the output to the lungs is obstructed the right ventricle develops thicker muscle to push harder, resulting in right ventricular hypertrophy.

最终由于进肺的出口梗阻，右心室努力的泵血使心肌越来越肥厚，造成右心室肥厚。
