320例健康体检者心电图Tp-Te间期的分析

Analysis of Tp-Te Interval In Electrocardiogram Of 320 Healthy Physical Examiners

目的分析健康人常规心电图Tp-Te间期。方法于2018年我院体检的健康人中,按年龄(20~30岁、31~40岁、41~50岁、51~60岁)及性别分为八个亚组,每组随机抽取40例,男女各160例。测量V2、V6导联的QT、Q-Tp间期,QT间期减去Q-Tp间期为Tp-Te间期进行分析。结果四个年龄组V2导联Tp-Te间期男性组为:86.22±6.68、86.21±8.19、86.24±7.57、86.35±7.24,女性组为:81.59±6.86、82.63±4.17、83.36±5.03、83.47±5.29;V6导联Tp-Te间期男性组为:80.25±4.92、80.85±6.61、82.02±7.88、82.53±8.65,女性组为:77.77±5.08、78.14±4.55、78.67±6.05、78.97±5.79。不同性别之间对比,男性组均较同导联同年龄组女性组高,p<0.05,差异有统计学意义;不同年龄组之间对比,差异无统计学意义。320例体检者V2导联Tp-Te间期为:84.51±6.69,V6导联为79.96±6.92,p<0.05,不同导联之间差异有统计学意义。总体Tp-Te间期:男性V2导联为86.25±7.37,V6导联为81.41±7.15;女性V2导联82.76±5.43,V6导联78.52±6.38。结论为建立Tp-Te间期的正常范围提供参考。

Objective To analyze the Tp-Te interval in Electrocardiogram of 320 Healthy Physical Examiners. Methods Randomly chosed 320 healhy peoples those examed in our hospital at 2018.And divided into eight groups according to the age(20 to 30, 31 to 40, 41 to 50 years and 51 to 60 years old) and the gender,40 cases in each group. Measured the QT interval and the Q-Tp interval of V2 and V6 lead, counted the Tp-Te interval with the QT interval minus the Q-Tp interval and analyzed. Results Between the four age groups,the TpTe interval of V2 lead in male group were: 86.22±6.68、86.21±8.19、86.24±7.57、86.35±7.24, and in female group were: 81.59±6.86、82.63±4.17、83.36±5.03、83.47 ±5.29;and the Tp-Te interval of V6 lead in male group were:80.25±4.92、80.85±6.61、82.02±7.88、82.53±8.65, in female group were: 77.77 ±5.08、78.14 ±4.55、78.67 ±6.05、78.97 ±5.79. The difference had statistically significant between different gender, but had no statistically significant between different age groups. The 320 cases’ Tp-Te interval of V2 lead was: 84.51±6.69, of V6 guide was 79.96±6.92, p< 0.05, the difference had statistically significant between different leads. And then the overall Tp-Te interval were: 86.25±7.37 in male at V2 lead, 81.41±7.15 in male at V6 lead;82.76±5.43 in female at V2 lead, 78.52±6.38 in female at V6 lead. Conclusions Provide the reference to set up the Tp-Te interval in normal persons.
