摘要
目的：用2种已报道的诊断标准研究一组心电图短QT间期者所占比例，并比较2种方法的异同。方法：随机选取547例健康人，做常规12导联心电图，准确测量QT间期，根据RR间期（RR）和心率（HR）计算QT间期校正值（QTc）和QT间期预计值（QTp），以QT〈QTp×88％（QTp法）及QTc〈363ms（〈60bpm），〈382[（60～90）bpm]（QTc法）为标准统计短QT例数。结果：总体QT均值（374±35）ms，QTc均值（414±29）ms，QTp法检出短QT间期16例（2．92％），QTc法检出短QT间期42例（7．67％），QTc法检出率明显高于QTp法。结论：国人心电图中用QTp法与QTc法检出短QT间期的结果明显不同。
Objective： We investigated the percentage of the short QT interval in randomized 547 normal people with two criterias and compared the difference of two results. Method： Measured the QT interval of the 547 electrocardiograms. Corrected QT was measured with Bazzet＇ s formula QTc = QT/RR^1/2 . Predicted QT was measured with Rautaharju＇ s formula QTp = 656（ 1 ＋ HR/100）. According to criterias of QT 〈 QTp × 88% and QTc 〈 363 ms （ 〈 60 bpm）, 〈 382 ms [ （60-90） bpm ], short QT subjects were counted. Result： Mean QT interval in 547 subjects was （374 ± 35） ms, mean QTc was （414 ± 29） ms. Short QT subjects obtained by two criterias were 16（2.92% ） and 42（7.67 % ） respectively. Conclusion：Significant difference was found between the results from the two criterias.
