Q-T离散度在慢性肺心病中的临床意义

Clinical Significances of Q-Td in Chronic Pulmonary Heart Disease

目的 :探讨Q T离散度 (Q Td)在慢性肺心病中的临床意义。方法 :观察 3 2例慢性肺心急性加重期病人Q Td、校正Q Td(Q Tcd)的变化 ,并与 2 5例慢性肺心病心功能代偿期及 3 0例正常人的Q Td、Q Tcd对照研究。结果 :慢性肺心病Q Td、Q Tcd较正常人明显延长 (P <0 .0 1) ,慢性肺心病急性加重期较缓解期Q Td、Q Tcd明显延长 (P <0 .0 1)。结论 :Q Td、Q Tcd在慢性肺心病中有重要临床意义 ,纠正使Q Td、Q

Objective:To explore clinical significances of Q Td in chronic pulmonary heart disease. Methods: The changes of Q Td and Q Tcd were observed in chronic pulmonary heart disease with acute exacerbation phase( n =32), heart disease with functional compensation( n =25), and normal group( n =30). Results:Compared with normal group,the patients in chronic pulmonary heart disease had longer Q Td?Q Tcd ( P <0.01).The patients in chronic pulmonary heart disease with acute exacerbation phase had longer Q Td and Q Tcd than in chronic pulmonary heart disease of remission phase ( P <0.01).Conclusion:Q Td?Q Tcd had important clinical significance in chronic pulmonary heart disease. Controlling reversible agents making Q Td?Q Tcd elongation can improve prognosis of the patients with pulmonary heart diseases.
