Rare Electrocardiographic Manifestation of Cystic Bronchiectasis in a 34-Year-Old Male

Himalayan P-waves (amplitude > 5 mm) are often known to be classically associated with congenital heart diseases with right to left shunt like tricuspid atresia, Ebstein anomaly, combined tricuspid and pulmonic stenosis, ischemic heart disease, restrictive cardiomyopathy, etc., where they indicate a dilated right atrium and tend to be persistent. This type of P-waves is rarely seen in long-standing bronchiectasis and is usually transient. It can be easily confused with congenital heart disease. Here we report a case of Himalayan P-waves in patient with bronchiectatic lung disease which is a rare entity.
