In some cases, right ventricular depolarization may not be visible.

在某些情况下，可能看不到右心室去极化。

Determining the presence or absence of extensive right ventricular involvement in ST elevation MI is challenging, but is of great clinical importance.

确定ST段抬高型心肌梗死是否存在广泛的右心室受累是一个挑战，但具有重要的临床意义。

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。

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。
