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]
- Tall, peak P waves in leads II, III, and avF which are consistent with right atrial enlargement
- Arrhythmias are frequent in this patient population.
- Because of the enlargement of the right atrium, the presence of atrial flutter and/or fibrillation should not be surprising[2] .
- In sinus rhythm, right atrial enlargement or abnormality (tall P waves on inferior leads) may be noted.
