ventricular hypertrophy

ventricular hypertrophy
hypertrophy of the myocardium of a ventricle of the heart, due to chronic pressure overload; it is manifest electrocardiographically by increased QRS complex voltage, frequently accompanied by repolarization changes.

Ventricular hypertrophy. Diagram contrasting the effects of left (LVH) and right (RVH) ventricular hypertrophy on the QRS vector. LVH exaggerates the normal pattern, causing deeper right precordial S waves and taller left precordial R waves. RVH shifts the QRS vector to the right, causing increased right precordial R waves.
