The palpation of dilated myopathy differs in that the impulse tends to be vigorous and brief. This is in contrast with the sustained impulse of the hypertrophied right ventricle. [5] A parasternal heave may also be felt in mitral stenosis. [6] A left ventricular heave (or lift) suggests the possibility of aortic stenosis. [citation needed]
Right ventricular hypertrophy is the intermediate stage between increased right ventricular pressure (in the early stages) and right ventricle failure (in the later stages). [11] As such, management of right ventricular hypertrophy is about either preventing the development of right ventricular hypertrophy in the first place, or preventing the ...
An important potential finding with echo is McConnell's sign, where only the RV apex wall contracts; [7] it is specific for right heart strain and typically indicates a large PE. [8] On an electrocardiogram (ECG), there are multiple ways RV strain can be demonstrated. A finding of S1Q3T3 [b] is an insensitive [10] sign of right heart strain. [11]
When viewed via cross section however, the right ventricle seems to be crescent shaped. [3] [4] The right ventricle is made of two components: the sinus and the conus. The Sinus is the inflow which flows away from the tricuspid valve. [5] Three bands made from muscle, separate the right ventricle: the parietal, the septal, and the moderator band.
Ventricular remodeling may include ventricular hypertrophy, ventricular dilation, cardiomegaly, and other changes. It is an aspect of cardiomyopathy , of which there are many types. Concentric hypertrophy is due to pressure overload , while eccentric hypertrophy is due to volume overload .
Right ventricular hypertrophy (thickening of the muscular walls of the right ventricle, this is a result of the increased amount of work the heart has to do) Ventricular septal defect (a hole exists in the septum that divides the left and right ventricles)

Ordinarily the JVP falls with inspiration due to reduced pressure in the expanding thoracic cavity and the increased volume afforded to right ventricular expansion during diastole. Kussmaul sign suggests impaired filling of the right ventricle due to a poorly compliant myocardium or pericardium. This impaired filling causes the increased blood ...
