Tricuspid stenosis is checked to diagnose _'s symptom
Laboratory and other inspections
Increase first, X-ray examination heart shadow obviously,back before right heart reason see atrium dextrum and superior vena cava outstanding, the maximum distance from centre line often> 5cm of the reason of atrium dextrum.
Second, electric picture II and V1 wire P wave amplitude of the heart> 0.25mV, brief on the atrium dextrum to increase.
Third, supersound aroused in interest to it pursues two-dimentional supersound to be aroused in interest to pursue, make a definite diagnosis of tricuspid stenosis, have high sensitiveness and specificity, four of views of the apex of the heart can see a leaf to increase thick, the relaxation one takes the form of round arch. Pass speed of maximum blood flow of the tricuspid valve mouth through what continuous Doppler determined, can calculate and step one and press difference. Colored Doppler learns to flow apparently and look like and can be seen a right ventricle side high speed of tricuspid valve " The flame shape " Efflux.
Fourth, heart conduit check to determine synchronously atrium dextrum and right ventricle are pressed in order to understand and step one and press difference.
Differential diagnosis
Display without accompanying lung extravasated blood with the intravenous extravasated blood of systemic circulation according to typical auscultation, can diagnose tricuspid stenosis. The intersection of wind and the intersection of worry and mitral stenosis person, until the intersection of ensiform process and place or the intersection of brestbone and left bottom flange have, inhale at the same time enhanced relaxation roar kinds of noise period, without obvious right ventricle expanding and lung extravasated blood, the mitral stenosis exists at the same time to brief on one. Atrial septal defect such as left is to part the flow on the right side largely, increase through the blood flow of the tricuspid valve, but one kind of noises that very brief relaxation roars in middle period after the tricuspid valve district hears the third heart sound. The above can be pursued to make a definite diagnosis of by the supersound aroused in interest.
