The Relatioe Between the Heart Volume and Stroke Volume Under Physiological and Pathological Conditions

Abstract

Investigations of the size of the heart volume and the stroke volume during rest were made both on healthy persons and on patients suffering from compensated and decompensated heart disease. Grollmann''s acetylene gas method was used. In healthy individuals, under standard conditions, the stroke volume and heart volume were each found to be approximately a positive linear function of the body surface. In healthy persons of different size, under standard conditions, the index heart volume/ stroke volume was found to be relatively constant. In cardiac insufficiency, the stroke volume fell below normal while the heart volume increased beyond normal.
