Overview
Right atrial enlargement can result from increased pressure in the pulmonary artery. A positive part of the biphasic P wave in lead V1 larger than the negative part indicates right atrial enlargement. Despite the increase in the height of the P wave, the width of the P wave does not change.
Differential Diagnosis of Underlying Causes of Right Atrial Enlargement
- Atrial aneurysm
- Atrial septal defect
- Cor pulmonale or right heart failure
- Ebstein's anomaly
- Tumor
- Pulmonic stenosis
- Tricuspid prolapse
- Tricuspid regurgitation
- Tricuspid stenosis
The EKG in Right atrial enlargement
Right atrial enlargement is defined as either:
