目的探求健康成人心电图额面和横面窦性QRS-T夹角的正常参考值范围。方法对100例健康成人(男、女性各50例,年龄23~58岁)的12导联心电图,测定额面和横面的窦性QRS波群和T波心电轴,然后测算额面和横面的寞性QRS-T夹角的绝对值(QRS-Ta)和相对值(QRS-Tr)。结果男性组、女性组和全组的额面窦性QRS-Ta值分别为19.0()°±12.88°(6.25°~44.25°)、18.86°±12.44°(5.52°~43.24°)和18.93°±1 2.60°(5.77°~43.63°);QRS-Tr值分别为-8.48°±21.47°(-50.56°^+33.60°)、-16.g4°±14.99°(-46.32°^+12.44°)和-12.71°±18.91°(-49.77°^+24.35°)。横面窦性QRS-Ta值分别为52.92°±24.97°(3.98°~101.86°)、30.60°±20.86°(10.29°~71.49°)和41.79°±25.49°(8.20°~91.72°);QRS-Tr值分别为52.80°±25.23°(+3.35°^+102.25°)、27.32°±25.08°(-21.84°^+76.48°)和40.06°±28.11°(-15.04°^+95.16°)。其中男、女性组间的额面QRS-Tr、横面QRS-Ta和QRS-Tr,差异有统计学意义,P值分为0.025、0.000和0.000。结论本文初步确定了我国健康成人QRS-Ta和QRS-Tr的正常参考值范围。
Objective To measure normal reference value of electrocardiographic sinus QRS-T angle of healthy adults in the frontal and horizontal planes for improving clinical application of these values. Methods Frontal and horizontal QRS-T angle and T-wave axis were measured from 12-lead electrocardiogram in 100 healthy adults with sinus rhythm（50 male and 50 female, aged from 23 to 58 years ）. The absolute and relative values of QRS-T angle （QRS-Ta and QRS-Tr） in frontal and horizontal planes were calculated. Results In male, female and the whole group, the fronal QRS-Ta were 19.00°- 12.88° （6.25°- 44.25° ）,18.86°± 12.44° （5.52°± 43.24° ）and 18.93° ±12.60° （5.77° - 43.63° ）, the QRS-Tr were -8.48° ＋ 21.47° （-50.56° - ＋33.60°）, - 16.94° ± 14.99° （-46.32° - ＋ 12.44° ）and - 12.71°± 18.91° （-49.77°-＋24.35° ）, the horizontal QRS-Ta were 52.92°- ＋ 24.97°（3.98° - 101.86° ）, 30.60° - 20.86° （10.29° -71.49° ） and 41.79° - 25.49°（8.20° -91.72° ）, the QRS-Tr were 52.80° ± 25.23° （＋3.35° - ＋102.25° ）, 27.32°± 25.08° （-21.84° - ＋76.48° ）and 40.06°-28.11° （-15.04°- ＋95.16° ）, respectively. There was a significant difference of frontal QRS-Tr angle, horizontal QRS-Ta and QRS-Tr between male and female group （P =0.025,0.000 and 0.000 respectively）. Conclusion The study preliminarily provides normal reference ranges of QRS-Ta and QRS-Tr in healthy adults.
