目的探讨房早联律间期/房早前周期比值与房性早搏诱发的阵发性心房颤动发生之间的关系并评价其价值。方法对24例房性早搏诱发的阵发性房颤患者的动态心电图分析,测量并计算诱发房颤的房早联律间期、房早前周期及房早联律间期/房早前周期比值,未诱发房颤的房早联律间期、房早前周期及房早联律间期/房早前周期比值。结果24例阵发性房颤患者中,诱发房颤的房早联律间期(452±53·3)ms,房早前周期(967±62·7)ms,房早联律间期/房早前周期比值0·47±0·08,未诱发房颤的房早联律间期(491±33·6)ms,房早前周期(896±50·3)ms,房早联律间期/房早前周期比值0·55±0·07,诱发房颤的房性早搏其房早联律间期,房早前周期及房早联律间期/房早前周期比值与未诱发房颤的房性早搏组相比,差异有统计学意义(P<0·01)。结论房早联律间期/房早前周期比值与阵发性房颤的发生呈负相关。
Objective To explore the relationship between the rate of atrial premature beats induced by atrial premature beats and the rate of paroxysmal atrial fibrillation induced by atrial premature beats (APLs) and evaluate its value. Methods 24 cases of atrial premature beats induced paroxysmal atrial fibrillation in patients with dynamic electrocardiogram analysis, measurement and calculation of atrial fibrillation induced atrial and anaphylaxis interval, anterior chamber circulation and atrial septal precordial / atrial early cycle Ratio, atrial fibrillation did not induce atrial premature beats interventricular septum, atrial early cycle and atrial septal early / interventricular / early anterior cycle ratio. Results Among the 24 patients with paroxysmal atrial fibrillation, the duration of atrial fibrillation induced by atrial fibrillation was 452 ± 53.3 ms, anterior chamber anterior chamber period was 967 ± 62.7 ms, The ratio of the earlier period of the room to the room was 0.47 ± 0. 08, the interval of atrial premature beats without intercourse (491 ± 33.6 ms), the room anterior chamber (896 ± 50.3 ms) Interval / anterior chamber ratio of 0.55 ± 0. 07, atrial premature beats induced atrial premature beats in their room interval, anterior chamber circulation and atrial septal / early anterior chamber ratio and not Compared with atrial premature beats induced atrial fibrillation, the difference was statistically significant (P <0.01). Conclusion Atrial premature rupture of sexual intercourse / anterior chamber ratio was negatively correlated with the occurrence of paroxysmal atrial fibrillation.
