What is the Bernheim effect and the reverse Bernheim effect?
The reverse Bernheim effect occurs when there is right ventricular pressure and volume overload that results in the interventricular septum bulging toward the left ventricle causing left ventricular diastolic impairment. This can cause symptoms of left heart failure and is actually due to right heart failure.
What is ventricular interdependence?
Ventricular interdependence (or ventricular coupling) is a phenomenon whereby the function of one ventricle is altered by changes in the filling of the other ventricle. This leads to increase in volume of one ventricle associated with a decreased volume in the opposite ventricle 1.

Why does right ventricular hypertrophy occur?
Right ventricular hypertrophy is usually caused by a lung-related condition or a problem with the structure or function of the heart. Lung conditions associated with right ventricular hypertrophy generally cause pulmonary arterial hypertension, which causes the arteries carrying blood to your lungs to narrow.
What is right ventricular pressure overload?
pressure overload of the right ventricle. Volume overload of the right ventricle with no or minimal change in pressure is basically associated with a preserved ejection fraction, while both end-diastolic volume and ejection fraction of the left ventricle are decreased.
How would you expect the pressure in the right ventricle to differ from the pressure in the left ventricle?
The left ventricle is thicker and more muscular than the right ventricle because it pumps blood at a higher pressure. The right ventricle is triangular in shape and extends from the tricuspid valve in the right atrium to near the apex of the heart.
Can thickening of the left ventricle be reversed?
LVH can often be corrected by treating the underlying problem causing the heart to work too hard. Depending on the type of damage that has occurred, treatment measures may include medications and heart-healthy lifestyle changes to help reduce the pressure in the heart.
Is ventricular hypertrophy reversible?
The Framingham Heart Study has shown that LVH is reversible and responds well to the lowering of blood pressure.
What is normal right ventricular systolic pressure?
RV Pressure Normal RV systolic pressure is 20–30 mmHg and normal diastolic pressure is 3–7 mmHg (Table 2). The RV waveform has a rapid upstroke and downstroke during systole.
