【摘要】 目的掌握克山病患者心输出量的变化特点，加强克山病防治。方法将１１４名克山病患者按病情分成潜在型、慢型两组，应用阻抗心动图、超声心动图测定心排出量。结果阻抗心动图法测得心搏出量（ＳＶ），潜在型（７９．１９±１６．９３）ｍｌ／次，慢型（６６．１０±１９．４５）ｍｌ／次；超声心动图法测得ＳＶ，潜在型（５１．０４±１５．７０）ｍｌ／次，慢型（４１．３０±１４．７１）ｍｌ／次。结论２种无创伤性心输出量测定结果是一致的，进一步证实克山病是低搏出量心肌病，为克山病心功不全早期诊断提供了新的无创性方法。更多还原

【Abstract】 Objective Master variance character of Keshan disease patient cardiac output and strengthen KD control. Methods 114 patients were class fied into two groups,chronic KD and potential KD.Stroke volume was measured by impedance cardiogram and Echocardiography. Results By impedance cardiogram:potential KD SV is (79. 19±16.93)ml,chronic KD SV is (66. 10±19. 45)ml;by Echocardiography: potential KD SV is (51.04 ±15.70)ml;chronic KD SV is (41.30±14. 71 )ml. Conclusions Results of the two kinds of noninvasive cardiac output is identica,which confirmed that KD is a low output cardiomyopathy.A new noninvasive method of early diagnose of cardiac insufficiency ws established.更多还原
