's symptom of the diagnosis of old pulmonary embolism
Diagnose that checks1,Electrocardiogram Electrocardiograms are different with size and involving the range differently of the thromboembolism lung artery pipe diameter pulmonary embolism hour. The lighter is not unusual, most patients are mainly shown as sinus tachycardia, lung P wave, the heavy one present lung worry S Q T. Some patients can present the bunch of right of incompleteness and prop up block. 2,Chest X-ray The regular chest slice often can't confirm the diagnosis of PE, the patient of about 10% of the pulmonary embolism has positive behavior, but lack the specificity. Mainly shown as the blood vessel lamination of regional lung is very thin, cardiac dilatation, lung artery high pressure, thorax last liquid, among rise the changes, half a side of diaphragms at soaking on piece, lung quality edema, lung. 3,The supersound aroused in interest is pursued Pursued to have 92% sensitiveness on bulk PE case and be close to 100% of the specificities by the oesophageal supersound aroused in interest, but a general pulmonary embolism patient is shown as it is normal. Unusually shown as the right ventricle is expanded, the artery high pressure of lung, playing a mouthful of vein expanding, interventricular septum to shift to the left ventricle. However, pursue to have greater value on diagnosis of the deep intravenous thrombus in the supersound aroused in interest. 4,The lung is kept in touch with poured into (V/Q) Show alikely The lung is kept in touch with poured into and scanned and revealed that has not poured into defect, can discharge pulmonary embolism. The normal one keeps in touch with the next section or more than one segment or bigger lung and pours into defect, or two or loud inferior segment pour into defect keep in touch with, in a very long one, highly brief on the existence of pulmonary embolism. 5,Lung angiography The ton of genuiness of pulmonary embolism that it is one " The gold standard " ,It is a inspection with wound. But the death probability checked is close to 1%, to the elderly, especially the serious disease patient has certain danger, seldom recommend this inspection. 6,Electron beam CT (EBCT)Can reveal the intersection of lung and blood vessel directly, have person who create check, to the intersection of pulmonary embolism and very much high detection rate (95% of sensitiveness, 97% of specificity, 93% of positive predicted value, negative predicted value 95%) ,Can substitute the regular lung artery radiography. It has similar function on lung artery thromboembolism above the lung Section with the artery radiography of lung that the chest spiral CT scans, can't detect inferior sections of following thromboembolism ' Positive rate 6% - 16% ) . 7,D- gathers the body to measure two times D- gathers the good mark thing whose body exchanged the fibrin degradation product united, gathers the body and is greater than 500 g/L as the positive value that is diagnosed with the blood plasma 1 - two, it judges sensitiveness of pulmonary embolism is 95% - 98% , D- gathers the body positively as the arranging and paying a home visit and breaking greater value of pulmonary embolism two times. D- two it gathers body to be can to increase physiology in the the elderly, greater than 500 g/L is so getting over 70 years old, its specificity diagnosed is only 14.3%. 8,Analysis of artery vim and vigour Show as the intersection of PaO2 and 20mmHg, low the intersection of carbonic acid and the intersection of blood and disease
