摘要/Abstract

摘要： 采用91导联体表电位标测法(BSPM)观察80例正常人Q-T_d^p(Q波起点到T波峰值间期的离散度),与同步12导联心电图Q-T离散度(Q-T_d)对照,探讨BSPM条件下测定Q-T_d的可行性。结果：① Q-T^p、Q-T_d^p、Q-T_c1d^p(Bazzett公式校正)、Q-T_c2d^p(Fridercia公式校正)分别为(292.69±37.75) ms、(36.77±7.40) ms、(40.23±9.04) ms和(40.11±7.73) ms；②Q-T_d^p与Q-T_d、Q-T_c1d^p与Q-T_c1d、Q-T_c2d^p与Q-T_c2d有良好的相关性；③3个年龄组(18～35岁、36～60岁、61～70岁)各参数间无显著性差异；④Q-T^p女性明显大于男性(P<0.05),其余各值男女性之间均无显著性差异。提示：BSPM测定 Q-T_d^p简便可行、较为准确,正常值可暂定为52 ms。

Abstract: To evaluate the feasibility of Q-T_d measurements under circumstances of body surface potential mapping(BSPM), QT_d^p(dispersion of interval of Q-wave onset to T-wave peak) was observed by using a computerized automatic mapping system in 80 normal individuals. The findings were compared with the 12-lead Q-T_d(the dispersion of Q-T interval). It was shown that: ① Q-T^p, Q-T_d^p, Q-T_c1d^p(corrected by Bazzett formula) and Q-T_c2d^p(corrected by Fridercia formula) were (292.69±37.75) ms, (36.77±7.40) ms, (40.23±9.04) ms and (40.11±7.73) ms respectively. ② Q-T_d and Q-T_c measured by BSPM and 12-lead ECG correlated well each other. ③ The differences of above parameters between three age groups(18～35 years, 36～60 years and 61～70 years) were not significant. ④ Q-T^p of female was longer than that of male(P<0.05), no significant difference was found in other parameters. In conclusion, Q-T_d^p measurement by BSPM might be more accurate and reliable than 12-lead ECG. The normal value of Q-T_d^p was less than 52 ms in this study.
