Q. Investigations process of constrictive pericarditis?
Electrocardiogram
Low voltage complexes can occur. Left atrial enlargement may be seen. Atrial fibrillation occurs in about one fourth of patients.
X-ray Chest
Cardiac enlargement occurs in almost half of the cases. Pericardial calcification is seen in chronic cases. Pericardium over the inferior surface and free wall of left ventricle, over the right ventricle and atrioventricular groove are common sites for calcification. Calcification is best seen in lateral film.
