Signs of right ventricular bounce: signs, symptoms, and causes

Description

On palpation of the left sternal border, an impulse with a peak at the head or middle of the systole may be observed under the examiner's hand.

Cause

Occurs in conditions that increase the right ventricular load and right ventricular hypertrophy.

Popular

Pulmonary embolism.

Pulmonary hypertension.

Less popular

Tetralogy of Fallot.

Severe mitral valve regurgitation

Severe mitral stenosis.

General mechanism

Increased burden causes right ventricular hypertrophy and causes the right ventricle to lie close to the chest wall.

Mitral valve regurgitation

In mitral regurgitation, the left atrium becomes a basal spacer because the increased volume during systole pushes the ventricles forward, making the heart's impulses perceptible through the chest wall, with a prolonged right ventricular bounce. easier and more perceptive. However, this rarely happens.
