摘　　要：目的探讨12导联动态心电图(AECG)与常规心电图(RECG)P波的差别,为12导联动态心电图P波的诊断标准提供依据。方法用常规12导联心电图的连接方式和12导联动态心电图的连接方式分别描记心电图,然后比较两种连接方式心电图P波的差别。结果两种测量方法,P波形态、电压、间期完全相同(形态相同指两者P波方向一致;电压相同指两者P波电压差别小于0.05mV;间期相同指间期差小于0.04s)共443例(73.8%)。形态存在差别共15例(2.5%),电压存在差别共109例(18.2%),间期存在差别共33例(5.5%)。结论两种连接方式,P波形态基本一致,不影响绝大多数心律失常的诊断,P波电压的差别较大,P波间期差≥0.04s33例,仅占5.5%,而且主要是AECG导联方式大于RECG导联方式,在分析12导联AECGP波时,可适当考虑这几方面因素。Objective To explore the difference of P waves between 12 leads ambulatory electrocardiogram （AECG） and routine electrocardiogram （ECG）. Methods The data of 600 samples for AECG and ECG were collected by routine way. The morphology, duration and the voltage of P wave in every Lead were measured and analyzed. Results Therewas no was difference in 443 subjects （73.8%） for P wave in morphology, duration and voltage of P wave. There was difference of morphology in 15 subjects. There was difference of voltage in 109 subjects（ 18.2% ）.There was difference of duration in 33 subjects （5.5%）. Conclusion For AECG and ECG, there was no difference of P wave in subjects of 97.5 %. It will not affect analyze for majority arrhythlnias.
