摘　　要：目的探讨正常人右胸导联心电图男女T波形态及变化规律。方法测量900例正常人右胸导联心电图，男女各450例，分析T波形态及变化规律。结果V3R→V6R直立T波出现率逐渐减少，倒置T波出现率逐渐增多。女性以倒置T波为主，男性直立T波多见，二者比较差异有统计学意义（P〈0．05）。V3R→V6R的T波可均倒置，女性多于男性（P〈0．01）；也可由直立→双相→平坦→倒置，男性多于女性（P〈0．01），但未见由倒置→直立。结论正常人右胸导联心电图T波形态男女差异显著，应引起临床注意。Objective To explore the difference of T wave shape in right precordial lead electro- cardiogram between normal male and female subjects. Methods Through measuring right precordial lead electrocardiograms of 900 normal human subjects, evenly separated by sex, T wave shape and pat- tern of change were compared and analysed between male and female subjects. Results From lead V3R to leads V6R, proportion of T waves in positive decreased and that in negative increased gradually. Dominating appearance of T wave was negative in female and positive in male and there was significant difference （P 〈 0.01 ）. Change pattern of T waves in leads V3R to V6R： Inversion can be seen in both leads and were seen more in female than male （P 〈 0.01 ）. Other manifestations were from upright to biphasic to flat to negative which were seen more in male than female （P 〈 0.01 ）. Conclusions There is a significant difference in T wave shape in right precordial lead electrocardiogram between normal male and female. It should be noticed in clinics.
