心房颤动患者临床症状与动态心电变化的关系探讨

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。

Studies of the Relations Between Symptoms and Ambulatory Electrocardiography in the Patients With Atiral Fibrillation.

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.
