The vasodilatory aspects of nitroglycerin reduce the blood return to the myocardium and this results in a corresponding reduction in the cardiac output. Blood pressure is often decreased and if it is lowered to the point of significant hypotension, the body will attempt to compensate with an increase in heart rate.
