Dilated Cardiomyopathy (DCM): Definition, Types, Diagnostics & Treatment

…etc. ) may ultimately lead to ventricular dilation. However, the term dilated cardiomyopathy (DCM) refers to idiopathic or genetic dilation of the left ventricle . Patients with…

Mitral valve stenosis

…leads to atrial hypertrophy and dilation. Atrial dilation causes a significantly increased risk of atrial fibrillation. The increase in left atrial pressure may also propagate…

Tricuspid regurgitation (TR/TI)

…Rheumatic heart disease. Dilatation of the right ventricle. Dilatation of the right atrium. Pulmonary hypertension. Left to right shunt. Right ventricular dysfunction due to pressure…

Mitral regurgitation

…wall stress, which can be alleviated by ventricular hypertrophy and dilation: Wall stress = (Pressure LV × radius LV ) / (2 × WT LV ) LV = left ventricle;…

Aortic regurgitation

…in the left ventricle and left atrium. Chronic aortic regurgitation leads to dilatation and hypertrophy of the left ventricle. Cardiac remodeling Ventricular dilatation and hypertrophy…

Arrhythmogenic Right Ventricular Cardiomyopathy / Dysplasia (ARVC, ARVD)

…TAD on the electrocardiogram. Echocardiography in ARVC Echocardiography shows global right ventricular dilation. The left ventricle and the septum are generally spared. Regional wall motion…

Pulmonary Embolism (PE)

…causes increased right ventricular load, which results in increased oxygen demand and dilatation of the right ventricle. Despite the dilation, myocardial ischemia will develop if…

Alcohol and Cardiovascular Disease

…left ventricular hypertrophy and mass. Initially, myocardial abnormalities may be subclinical. Progressive dilation can subsequently impair left ventricular ejection fraction. Enlargement of the left ventricle…

Left Ventricular Function

…actually a stronger predictor of death than the atherosclerotic burden. Assessment of the size, mass, geometry, and function of the left ventricle is fundamental for…

The QRS complex: ECG features of the Q-wave, R-wave, S-wave & duration

…to the left and downwards ( Figure 7 ). The explanation for this is as follows: The vector resulting from activation of the right ventricle does not…
