When left atrial enlargement occurs, it takes longer for cardiac action potentials to travel through the atrial myocardium; thus, the P wave also lengthens. Therefore, the criteria for diagnosing ...

This is referred to as p-pulmonale since lung disease can cause severe right heart strain and right atrial enlargement. Thus, the P wave height becomes larger. The ECG criteria for diagnosing ...

[2] A typical EKG shows an axis between 0 and +120°, an RSR is often present in V1, especially in significant defects. A radiogram may show enlargement of the right chambers in the lateral view ...
