Overview

The electrocardiogram of patients with tricuspid stenosis can demonstrate a sinus rhythm with or without signs of right atrial hypertrophy. Patients with tricuspid stenosis can experience frequent arrhythmias, particularly atrial flutter and/or atrial fibrillation due to the enlargement of the right atrium.

Electrocardiogram

An ECG may be not helpful in the diagnosis tricuspid stenosis but it is an useful tool to identify the concurrent conditions such as atrial fibrillation.
Findings on an ECG suggestive of tricuspid stenosis include:^[1]^[2]^[3]^[4]
- Tall, peak P waves in leads II, III, and avF which are consistent with right atrial enlargement.
- Arrhythmias are frequent in this patient population.
- Atrial flutter and/or fibrillation should not be surprising.
- Left atrial hypertrophy and enlargement can be noted in patients who are having mitral disease that is associated with rheumatic heart disease.
