摘要
为探讨校正ＪＴ间期离散度（ＪＴｅｄ）对扩张型心肌病（ＤＣＭ）预后的价值。检测３１例ＤＣＭ病人及３１例正常人心电图校正ＪＴ间期（ＪＴｃ）及ＪＴｃｄ，ＤＣＭ组同时行心功能、超声心动图、动态心电图检查。结果：①ＤＣＭ组与对照组的ＪＴｃｄ有显著差异（Ｐ＜０．００１）；②ＤＣＭ组ＪＴｃｄ与左室壁厚度、左室舒张末径无关（Ｐ＞０．０５）；③ＤＣＭ组心功能好坏、有无复杂性室性心律失常、死亡与否的ＪＴｃｄ之间无显著差异（Ｐ＞０．０５）。提示ＪＴｃｄ在ＤＣＭ患者中较大，但也许不能作为预测预后的指标。
In order to study value of rate corrected JT interval dispersion (JTcd)for prognosis in dilated cardiomyopathy (DCM).Rate corrected JT interval(JTc) and JTcd were measured in the electrocardiogram in 31 patients with DCM and 31 mormal subjects.Results:①JTcd was significant different between DCM group and control group(P<0001);②JTcd was not significantly related to left ventricular wall thickness,left ventricular end diastolic dimension in DCM group(P>005);③JTcd was no significant difference among patients with and without poor cardiac function,complicated ventricular arrhythmia or death in DCM group(P>005).Revealing that value of JTcd is greater in DCM,but it perhaps might not be considered as an indicator for prognosis prediction.
