Laboratory and other inspection _'s symptoms of tricuspid stenosis
(1) Increase X-ray examination heart shadow obviously,back before see atrium dextrum not expanded location right heart reason obviously, the superior vena cava is outstanding, but there is not lung arteriectasis. The maximum distance from centre line of the right room edge is greater than 5cm.
(2) It is loose to check the atrium dextrum the electrocardiogram, 2 and 1 lead and unite P wave high and sharp; Amalgamate mitral stenosis at the same time because of most tricuspid stenosis patients, so the electrocardiogram also often shows one pair of atriums loosely. There is no manifestation of right ventricular hypertrophy.
(3) What the supersound aroused in interest is observed while pursuing to check change and mitral stenosis of the tricuspid valve is similar, M -type supersound pursue, reveal petals of leaf increase thick, the intersection of EF and slope of frontal lobe slow down, the intersection of relaxation and with separate one, take the form of contradictory sport, the intersection of tricuspid valve and calcification and increase thick issue often while being aroused in interest; Two-dimentional supersound aroused in interest to pursue to diagnose relatively helpful tricuspid stenosis, its characteristic is that a leaf of relaxation takes the form of the garden and joins the form, increase thick, a leaf is movable and limited. Doppler's supersound can be seen a right ventricle side high speed of tricuspid valve " The flame shape " Efflux.
(4) The heart conduit checks and shows the right room to press and increase to step one and press difference with the tricuspid valve.
Diagnose it according to typical noise, atrium dextrum expanding and symptom and physical sign of systemic circulation extravasated blood, can generally make diagnosis, the feasible right heart conduit inspection of the person who has difficulty on diagnosing, if the tricuspid valve steps difference of a diastolic pressure in 0.27kPa( 2mmHg) equally The above, can diagnose as tricuspid stenosis.
