【摘要】 探讨心房颤动 (AF)患者临床症状与动态心电变化的关系。记录 6 7例AF病人的 2 4h心电图 ,并记录临床症状及发生时间 ,比较症状发生时动态心电的变化特征。结果 :①持续性AF与阵发性AF相比、夜晚与白天相比、使用与未使用抗心律失常药物相比 ,其病人的平均心室率显著较慢 ,发生长间歇的频次显著较高 ,而不同病因的AF患者之间相比 ,特发性AF其发生长间歇例数及频次均少于其他原因的AF ;②窦性心律转为AF、心室率过快 ( >10 0次 /分 )或过慢 ( <5 0次 /分 )、长间歇 >3s、长间歇连续 3次以上发生均可能导致临床症状的发生 ,其中以心悸、呼吸困难最为常见 ,头晕、黑较少见 ,晕厥最少见。结论 :AF患者的临床症状与AF类型以及一些特征性的动态心电变化有关。更多还原

【Abstract】 To investigate the relations between symptoms and ambulatory electrocardiolography(ECG) in patients with atrial fibrillation(AF),24 hours ECG,symptoms,and the time that symptoms occurred were recording,then these data were analyzed .Results:①Comparing with permanent AF and proximal AF,at the night and on the day,used and un-used antiarrhythmia drugs,the former had a significant slower averaged rate of ventricular beats and a higher frequency that presented long RR intervals.On the other hand,the patients with idiopathic AF had a significant lower frequency of long RR intervals than the patients with other causes;②When the patients with AF presented the characteristic cardioelectricity changes that sinus rhythm turned to AF,too fast (>100 beats/min) or too slow (<50 beats/min) rate of ventricular beats,too long RR interval (>3 s),and long RR intervals continued more than 3 times,the symptoms such as palpitation and short breath were the most common,syncope was the most uncommon symptom.Conclusions: The symptoms of patients with AF are related with the type of AF and the characteristic ambulatory ECG changes.更多还原
