RAE is typically diagnosed using a combination of clinical signs and diagnostic tests. Histological examination is not commonly used for initial diagnosis but can provide insights into the extent of structural changes. Some diagnostic methods include:
Electrocardiogram (ECG): An ECG can show signs of right atrial enlargement, such as tall P waves in lead II. Echocardiography: This imaging technique provides a visual assessment of the atrial size and function. Histological Examination: Tissue samples obtained through biopsy can be examined under a microscope to assess the degree of hypertrophy and fibrosis.
