12导联动态心电图与常规心电图P波差别的研究

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0.05 mV;间期相同指间期差小于0.04 s)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≥0.04 s 33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AECG P波时,可适当考虑这几方面因素.

The Difference of P Waves between 12 Leads Ambulatory Electrocardiogram and Routine Electrocardiogram

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 arrhythmias.
