摘　　要：目的 :探讨甲状腺上动脉峰速与心率乘积诊断甲亢的价值。方法 :对经临床及核医学检查证实的65例甲状腺功能亢进 (甲亢 )、 2 9例亚临床甲状腺功能低下 (亚甲低 )及 2 1例甲状腺功能低下 (甲低 )进行了彩色多普勒超声检查 ,测量并计算甲状腺上动脉峰速与心率乘积 (PV H) ,并与正常组进行对照。结果 :甲亢组的 PVH测值显著高于亚甲低组、甲低组及正常组 (P<0 .0 1 )。若以 PV H≥ 55作为诊断甲亢的标准 ,其敏感性、特异性及准确性分别为 93.8% ,96.0 %及 94.8% ,明显优于采用 Vmax≥ 0 .7m/s诊断甲亢的方法 (P<0 .0 1 )。结论 :应用PV H诊断甲亢 ,简单、实用 。Objective:To explore the value of diagnosing hyperthyroidism by product of the peak velocity of superior thyroid artery and heart rate.Methods:Sixty five patients with hyperthyroidism(HET),29 with subclinical hypothyroidism(SHT)and 21 with hypothyroidism(HOT)diagnosed in clinic and confirmed by nuclear medicine examinations underwent color Doppler sonography and the product of the peak velocity of superior thyroid artery and heart rate(P VH ) were measured and compared with the normal.Results:The P VH of HET were significantly higher than those of SHT,HOT and normal (All P <0 01) respectively.While P VH ≥55 was used as the diagnostic criterion for HET,the sensitivity,specificity and accuracy were 93 8%,96 0% and 94 8%,respectively.P VH was superior to Vmax≥0 7m/s for diagnosing HET( P <0 01).Conclusions:Detecting HET by P VH is a simple and practical method with high diagnostic accuracy rate.
