摘要
对 18例高血压心脏病合并房颤病人房颤转复前后的心电图进行比较 ,发现房颤时 Q RS波振幅较窦性心律时明显下降 ,Σ QRS平均下降 17.9% (182 .5± 40 .7比 14 9.2± 33.6 m m ,P <0 .0 5 )。同期超声心动图提示房颤时 QRS波振幅降低与左室容积减少有关。建议对房颤状态下心电图判断左室肥厚的 QRS波振幅标准应相应降低 。
Electrocardiography(ECG) before and after cardioversion of atrial fibrillation(Af) in 18 cases of hypertensive heart disease and Af was compared.It was found that QRS voltage was much lower in Af than in sinus rhythm,and Σ QRS decreased by 17.9% (182.5±40.7 vs 149.2±33.6 mm,P<0.025).Simultaneous echocardiography indicated that QRS voltage reduction in Af was related to the left ventricular volume decrease.This suggests that ECG standard for detecting left ventricular hypertrophy in Af should be reduced relevantly,or it would influence the sensitivity.
