TABLE 7-1 ■ Variations and Abnormalities of the Ventricular Impulses
When a ventricle works under conditions of chronic pressure overload or increased afterload, its walls gradually thicken or hypertrophy. Volume overload (increased preload), in contrast, produces dilatation of the ventricle as well as thickening of its walls. A hyperkinetic impulse results from increased stroke volume and does not necessarily signify heart disease. An impulse may feel hyperkinetic when the chest wall is unusually thin.
