This is referred to as “LVH with strain” or “LVH with repolarization ... If the R wave is greater than 12 mm in amplitude, LVH is present. Sokolow-Lyon Criteria: Add the S wave in V1 plus ...

However, the amplitude of the P wave is exaggerated due ... to as p-pulmonale since lung disease can cause severe right heart strain and right atrial enlargement. Thus, the P wave height becomes ...
