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.
