Left axis deviation occurs when the QRS axis falls between -30 and -90. There are a variety of causes, including left anterior fascicular block and left ventricular hypertrophy.

Pathologic left ventricular hypertrophy can occur in the setting of hypertrophic obstructive cardiomyopathy even in the absence of increased afterload.

Pathophysiology of Right Ventricular Failure The main determinants of right ventricular function, like those of left ventricular function, are preload, afterload, contractility, and lusitropy.

Echocardiography is widely used as the primary test for diagnosis of left ventricular hypertrophy, but there is a limit to distinguishing minute structural differences in the ventricle with the ...

There is an adequate body of evidence that indicates that left ventricular hypertrophy is a marker for a shorter-than-normal life span.

Left ventricular noncompaction is characterized by deep trabeculations in the LV endocardium in association with left ventricular hypertrophy, dilation or hypertrophy/dilation. Noncompaction of the ...

A 78-year-old man was evaluated in the cardiology clinic because of biventricular myocardial wall thickening, mitral regurgitation, and ventricular arrhythmias. In his 20s, hypohidrosis and sports- ...
