药物转复87例房室结折返性心动过速临界心率探讨

Critical heart rate distribution duration drug cardioversion of atrioventricular nodal reentrant tachycardia

目的探索房室结内折返性心动过速药物转复心率变化的规律。方法记录发病时初始心率(初始心率)、转复时心率(终末心率),计算初始和终末心率的差值(差值),对三部分数据分别做统计描述、同时做分布类型检验。结果初始心率、终末心率、差值的最大值分别为280、258、41次/分;最小值分别为143、109、15次/分;均值分别为193、167、26次/分。终末心率和差值分布类型检验值kolmorol-smirnol分别为0.097、0.973;P分别为0.071、0.106。结论差值和终末心率分别为均数和标准差是26、5.37,167、34.93的正态分布。

Objective To explore the variation type of heart rate duration cardioversion of atrioventricular nodal reentrant tachycardiac（AVNRT） o Methods Respectively to record the heart rate of AVNRT patients before and after cardloveision（initial heart rate -IHR and terminal heart rate -THR）. Calculating their difference （D）. P- Rocessing statistical analysis to related data. Results The maximums of IHR、THR and D are respectively 280,258,41beats/rain; the minimums respectively are 143、109,15 beats/rain;the medians respectively are 193,167,26 beats/rain. The test of mormality of THR and D（Shapire-Wilk） are 0. 097 、0. 973 ; p respectively are 0. 071、0.106. Conclusion The statistical distribution types of D and THR are of mormality（26、5. 37 ;167、34. 93） .
