Hemodynamic changes occurring with spontaneous atrioventricular dissociation, left ventricular pulsus alternans, a rise in systemic arterial pressure, and the injection of angiographic contrast material support the hypothesis that in a given patient with idiopathic hypertrophic subaortic stenosis the degree of left ventricular outflow obstruction is determined by three factors: the force of left ventricular contraction, ventricular volume, and ventricular afterload.
