摘　　要：目的探讨甲状腺功能亢进患者的右心室舒张功能。方法甲状腺功能亢进患者和正常对照组各40例,常规超声心动图检查后,应用TDI在标准心尖四腔切面获得右室游离壁及室间隔三尖瓣瓣环处的峰值速度参数Sm、Em、Am,所有参数进行组间比较。结果传统采用的三尖瓣血流E/A值两组之间差别无统计学意义(P值>0.05),而应用TDI技术测量甲状腺功能亢进患者Em、Am、Em/Am与正常对照组比较差异有统计学意义(P值<0.01)。结论甲状腺功能亢进患者右室舒张功能受损。应用TDI技术评价甲状腺功能亢进患者右室舒张功能较传统超声心动图检查具有优越性,可为临床治疗提供重要依据。Objective To approach the right ventricular diastolic function in of patients with hyperthyroid.Methods The subjects consisted of 40 patients with hyperthyroid and 40 matched normal control ones.Tricuspid annular pulsed-wave rate of E/A were measured by traditional echocardiographic, the peak value of tricuspid annular systolic velocity（Sin）, early diastolic velocity（Em）, late diastolic velocity （Am）were analyzed by TDI. Results The early diastolic velocity（Era）, late diastolic velocity（Am）, ratio of Em/Am in patients were different from those of control group（P〈0.01）.The traditional E/A had no significant difference between these two groups（P〉0.05）.Conclusions The right ventricular diastolic function was impaired in patients with hyperthyroid.TDI had more superiority than th traditional echocardiographie to reflect the variation of the right ventricular diastolic funetion, and it can provide important evidence for clinical treatment.
