Overview
The electrocardiogram (ECG) in tricuspid regurgitation (TR) might have no significant abnormalities. Findings suggestive of right atrial enlargement and hypertrophy might be present secondary to either pulmonary hypertension or to the hemodynamic consequences of TR itself. In case of TR secondary to left heart disease, the ECG might demonstrate changes related to the underlying condition.
Electrocardiogram
Right Atrial Enlargement
ECG findings of right atrial enlargement include:
Shown below is an ECG demonstrating large P waves in leads to II,III, and aVF which have a P-wave height greater than 2.5 mm consistent with right atrial enlargement:
Right Ventricular Hypertrophy
ECG findings of right ventricular hypertrophy include:
- Right axis deviation of +90 degrees or more
- The R wave in V1 is 7 mm or more in height
- RV1 + SV5 or SV6 = 10 mm or more
- R/S ratio in V1 = 1.0 or more
- S/R ratio in V6 = 1.0 or more
- Late intrinsicoid deflection in V1 (0.035+)
- Incomplete RBBB pattern
- ST T strain pattern in 2,3,aVF
- P pulmonale or P congenitale
- S1 S2 S3 pattern in children
- Tall R wave in V1 or qR in V1
- R wave greater than S wave in V1
- R wave progression reversal
- Inverted T wave in the anterior precordial leads
Shown below is an ECG tracing from lead V1 demonstrating right ventricular hypertrophy.

Adolescents (DO NOT EDIT) [1]
| Class I |
| "1. An ECG is indicated for the initial evaluation of adolescent and young adult patients with TR, and serially every 1 to 3 years, depending on severity. (Level of Evidence: C)" |
| Class IIb |
| "1. Holter monitoring may be considered for the initial evaluation of asymptomatic adolescent and young adult patients with TR, and serially every 1 to 3 years. (Level of Evidence: C)" |
