摘　　要：目的探讨甲状腺机能亢进性心脏病的Q-T离散度(Q-Td)及其心率校正值(Q-Tcd)改变的临床意义。方法选择53例临床确诊为甲状腺机能亢进性心脏病患者的体表12导联心电图并与50例单纯甲状腺机能亢进患者及50例正常人作对照。结果甲状腺机能亢进性心脏病组、单纯甲状腺机能亢进组及正常人组Q-Td分别为(53.9±10.2)ms、(31.8±7.9)ms、(29.8±6.2)ms;Q-Tcd分别(62.0±12.4)ms、(36.5ms±8.5)ms、(32.8±6.8)ms显示甲状腺机能亢进Q-Td及Q-Tcd明显延长(P<0.01)。结论揭示Q-Td、Q-Tcd延长对临床甲状腺机能亢进性心脏病的诊断有一定的参考意义。Objective To investigate the clinical significance for Q-T dispersion degree (Q-Td) and change of heart rate correct value (Q-Tcd) in hyperthyroid heart disease. Methods Surface 12 electro-cardio graphic lead was used in 53 cases of hyperthyroid heart disease (group 1). 50 cases of hyperthyroid (group 2)and 50 cases of normal people (group 3) were control groups.Results Values of Q-Td in group1,2, and 3 were (53.9±10.2)ms, (31.8±7.9)ms and (29.8±6.2)ms respectively. Values of Q-Tcd were (62.0±12.4)ms, (36.5±8.5)ms and (32.8±6.8)ms. Q-Td and Q-Tcd in hyperthyroid heart disease were lengthened significantly. Conclusions There is clinical significance of Q-Td and Q-Tcd lengthening in hyperthyroid heart disease.
