Abstract
The effect of the straining procedure upon the systemic and pulmonary circulations in normal individuals and patients with mitral stenosis of several grades is described. The response of patients with severe mitral stenosis to this procedure differs from that of normal individuals and individuals in whom the mitral stenosis is only of acoustic significance. The difference is based upon the altered dynamics created by the stenotic mitral valve. It is possible that the presence or absence of the reflexogenic post-straining bradycardia and its degree with a standardized Valsalva-like maneuver may be used as a clinical bedside index of the degree of mitral stenosis.
