Right Ventricular Strain

Electrocardiographic Features

Repolarisation abnormality due to right ventricular hypertrophy or dilatation. ST depression and T wave inversion in the leads corresponding to the right ventricle.

  • The right precordial leads:  V1-3, often extending out to V4
  • The inferior leads:  II, III, aVF, often most pronounced in lead III as this is the most rightward-facing lead.

**NB. Compare this to the left ventricular strain pattern, where ST/T-wave changes are present in the left ventricular leads (I, aVL, V5-6).

Causes

Associated with increased pulmonary artery pressures in the setting of acute or chronic right ventricular hypertrophy or dilatation:


ECG Examples

Example 1
ECGH RVH Right ventricular hypertropy RV Strain

Right ventricular hypertrophy 

  • Typical right ventricular strain pattern: ST depression and T-wave inversion in V1-4 (plus lead III), in this case due to right ventricular hypertrophy.

Example 2
ECG Massive Pulmonary embolus RVH RV Strain
Acute right ventricular dilatation due to massive PE. 

Right ventricular strain pattern involving both the precordial and inferior leads:

  • T-wave inversions are seen in the right precordial (V1-4) and inferior leads (III, aVF) in this patient with acute right ventricular dilatation due to massive pulmonary embolism.
