摘　　要：目的探讨短Q-T间期的临床意义。方法对15例短Q-T间期患者的临床资料进行回顾性分析。结果15例中男性9例、女性6例;脑出血4例,急性心肌梗死5例,肺源性心脏病心力衰竭2例,2型糖尿病伴多器管衰竭2例,颅脑挫伤2例;实测Q-T间期均符合短Q-T间期(Q-T间期<320ms[1];QT<QTp×88%[2];QTc≤340ms[3])的标准,其中6例出现室性心动过速、心室颤动,9例出现缓慢性室性逸搏心律,最终经抢救无效死亡;实验室检查:电解质指标均在正常范围,低氧血症8例、酸中毒10例。结论Q-T间期缩短在一定的临床疾病背景下,是一种严重的心电现象,是患者临终心电图表现之一,应引起临床医师高度重视。Objective To investigate the clinical significance of the short Q - T interval syndrome. Methods Analyzing retrospectively on the clinical materials of 15patients with short Q - T interval syndrome. Results Of the 15 subjects （9 male and 6 female）, there were 4 eases with brain hemorrhage, 5, acute myocardial infarction, 2, cor pulmonale and heart failure, 2, type 2 diabetes with multiple organ failure （MOF）, and 2, cerebral contusion and laceration. All their Q -T interval meet the diagnostic criteria of the short Q - T interval （ Q - T 〈 320mm, Q - T 〈 QTp × 88%, QTc≤340mm）. Although with emergency treatment, they all died, 6 eases died from ventrieular tachycardia and ventricular fibrillation, and the rest, slow ventricular escape rhythm. The laboratory test indicated that the electrolytes criterion were normal in all patients, 8 eases had hypoxemia and 10, acidosis. Conclusion For patients with organic heart disease, the reducing Q -T interval is a serious ECG phenomenon, happening on the deathbed.
