摘　　要：目的　观察 QT离散度 (QTd)在慢性充血性心力衰竭 (CHF)患者中对猝死的预测。方法　收集近 2年诊断明确的 CHF病人 6 2例作为观察对象 ,并选择 47例正常人为对照 ,由专人测定患者入院时的首次常规心电图 QT间期 ,测量导联每份心电图不少于 7个。结果　 CHF病人的 QTd和 QTcd均明显大于正常人 (P<0 .0 5 )。结论　 QTd可作为CHF病人猝死的简单、实用的预测指标之一。Objective To observe the QTd in the patients with chronic congestive heart failure (CHF) and predict their probable sudden cardiac death.Methods In last two years 62 cases clearly diagnosed as CHF were collected as eligible subjects and were compared with 47 healthy persons.In addition,experienced technicians were specially assigned to take the first QT interval of routine electrocardiogram when the patients were admitted to hospital,and not less than 7 copies of equivalent electrocardiograms were examined.[WT5”HZ]Results The QTd and QTcd of the CHF sufferers were obviously higher than those of the healthy persons (P<0.05).Conclusion The authorssuggest that QTd be regarded as one of the simple and practical indices for predicting the sudden cardiac death of the patients with CHF.
