Mitral Diastolic, or Pre-systolic (Mitral Ob¬ structive).—Maximum intensity at left apex; con¬ ducted well to axilla, feebly or not at all up aorta; sio-nifies constriction of the mitral orifice. 3. Aortic Systolic (Aortic Obstructive).—Maxi¬ mum intensity at base of heart; conducted strongly up aorta, feebly or not at all towards axilla ; sig¬ nifies constriction of the aortic orifice. 4. Aortic Diastolic (Aortic Regurgitant).—Maxi¬ mum intensity at base of heart; conducted best downwards towards ensiform cartilage, feebly up aorta, and not at all towards axilla ; signifies in¬ sufficiency of aortic valves, and regurgitation of blood into left ventricle.
