Pulmonary valve insufficiency is a disorder involving a defect of the valve located in the pulmonary artery.
肺動脈瓣閉鎖不全是一種疾病,缺陷位於肺動脈(翻起來很怪 involving指包含但不知道怎翻比較好)
The pitch and location of the murmur will help a physician determine if the cause is pulmonary valve insufficiency. An electrocardiogram (EKG) can detect flow changes. Echocardiography with color Doppler can usually detect regurgitation of blood in the area. This exam is done with ultrasound imaging. A chest x ray may show prominence of the pulmonary artery. In some cases, angiocardiography, or x ray of the arteries and vessels with injection of a dye, may be ordered.
心雜音的強度位置將可以幫助醫生判斷的原因是否為肺動脈閉鎖不全, 心電圖可以檢測流量的變化。超聲彩色多普勒，通常可以檢測在該地區的血液回流, 這項檢查是超聲影像. 胸部x光可以顯示突出的肺血管,在某些情況下,可依醫囑執行心血管攝影術,動脈血管注射顯影劑
(上面也是亂翻的= =)
On its own, pulmonary valve insufficiency is seldom severe enough to require treatment.
就其本身而言, 肺動脈瓣閉鎖不全很少嚴重到需要治療,抗生素通常建議在牙齒工作前使用
(這句也怪)
Since there are few or no symptoms and the disorder is a structural defect, alternative treatment may have only limited usefulness. Proper diet, exercise, and stress reduction may help control hypertension. Coenzyme Q10 and hawthorn (Crataegus laevigata) are two important nutrients to nourish the heart. Antioxidant supplements (including vitamins A, C, and E, selenium, and zinc) can help keep the tissues of the whole body, including the heart, in optimal condition.
由於有很少或根本沒有症狀，這種疾病是一種結構性缺陷，選擇性治療作用有限, 適當的飲食，運動，並強調減少可能有助於控制高血壓。輔酶Q10和山楂（山楂laevigata ）是兩個重要的養分滋養的心臟。抗氧化補充劑（包括維生素A ， C和E ，硒，鋅）可以幫助整個身體組織保持,包括心臟，在最佳條件。
Patients with this disorder may never experience limitations from pulmonary valve insufficiency
病患可能從沒經歷過肺動脈閉鎖不全這種疾病的限制因素
