创新I导联右耳与左上肢连接方式对心电图的影响

Effect of innovative leads I connection of right ear and left arm on ECG

目的探讨创新I导联右耳与左上肢连接方式对心电图的影响。方法收集男女各58例共116例受检者的常规标准十二导联心电图和右耳与左上肢创新连接方式记录的十二导联心电图，经统计学处理后进行对比分析。结果男性组58例受检者用标准连接方式和用创新连接方式记录得出的心电图大致相同，女性组58例受检者用标准连接方式和用创新连接方式记录得出的心电图也大致相同。结论当受检者因右侧上肢外伤、烧伤、截肢、安装假肢、帕金森病等情况不便安置电极，无法记录常规心电图时，可将右上肢电极安置在右耳，同样可以记录到满意的心电图为临床提供诊断依据。

Objective To investigate the effect of innovative leads I connection of right ear and left arm on ECG. Methods 116 cases with 58 cases of men and women each were equally divided into male and female groups and analyzed. Through collecting the standard ECG and the ECG with innovative connection of right ear and left arm, using the statistic SPSS software, a comparative analysis was carried out between the two groups. Results The standard ECG and the innovative leads I connection were both used in 58 cases of male group, however, there was no significant difference found in the ECG records. Same experiment was also carried out in 58 cases of female group, and the same result obtained as the male group. Conclusion If the right upper limb of the patient is in the circumstances such as traumatic, burns,amputation, installed artificial limb etc, or when the patient is in the trouble of Parkinson Disease, the electrode thus can not he placed in the right upper limb. In this situation, the electrode can be placed in the right ear of the patient, which will also receive satisfactory ECG record for clinical reference.
