In this condition the right atrium is enlarged with downward a displacement of the tricuspid valve into the right ventricle. This partially explains the tall peaked p waves in the inferior leads. Note the P wave in lead II is greater than 2 mm in height. There is also a first-degree heart block which is often seen with these patients. Curiously higher grade blocks are rare. The QRS complex shows a right axis deviation and a terminal S wave in the V 6 derivation. Atypical right bundle branch block can be seen with this condition.]] | |||
