Overview

Electrocardiogram

Right Atrial Enlargement

ECG findings of right atrial enlargement include:

  • A P wave >2.5 mm in leads II, III and aVF
  • A P wave >1.5 mm in lead V1

Shown below is an ECG demonstrating large P waves in leads to 2,3, and aVF which have a P-wave height greater than 2.5 mm consistent with right each one 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

Shown below is an ECG demonstrating right ventricular hypertrophy. Note that R wave > the S wave in V1.

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)"
