摘要

目的  探讨常规12导联同步心电图上P波时限指标异常预测阵发性房颤的价值。方法  选取我院门诊及住院的阵发性房颤患者100例作为房颤组,并选取心电图正常的窦性心律体验者80例作为对照组。测量两组常规12导联同步心电图上P波离散度(P-wave dispersion,PWD)及P波最大时限(Pmax),并比较两者的差异。结果  房颤组患者的PWD明显高于对照组[(51.08±12.03) ms vs. (33.19±8.98)ms],而Pmax也高于对照组[(121.57±15.33) vs.(101.94±9.89)],且两组差异均有统计学意义(P均<0.05)。结论  通过测量常规12导联同步心电图上的P波指标可以早期筛查阵发性房颤患者,对该类人群进行早期诊断及治疗可降低脑卒中发病率。

Abstract

Objective  To explore the value of abnormality of P-wave duration  indexes in routine 12-lead simultaneous ECG in predicting paroxysmal atrial fibrillation(PAF). Methods  A total of 100 outpatients and inpatients with PAF in our hospital were selected as  research objects(AF group) while 80 cases who had taken health examination  with normal sinus rhythm were selected as  control group. The P-wave dispersion(PWD) and the maximum duration of P-wave in routine 12-lead simultaneous ECG were measured and compared between the two groups. Results  PWD of the patients in the AF group is significantly higher than that in the control group[(51.08±12.03) ms vs. (33.19±8.98) ms], and the maximum P-wave duration is also significantly higher than that in the control group[(121.57±15.33) vs. (101.94±9.89)], both with statistically significant differences(P<0.05). Conclusion  By measuring P-wave indexes in routine 12-lead simultaneous ECG, patients with PAF can be screened early. Early diagnosis and treatment help to reduce the incidence of stroke among this kind of population.
