心房纤颤是最常见的心律失常之一,它多见于器质性心脏病患者,心房纤颤常合并较长的R-R间期(≥1.5S),由于夜间心率较慢,更易发生长间期,危及患者生命,本文主要是对心房纤颤伴长R-R间期患者的24小时动态心电图进行分析和探讨其临床意义。目的:对心房纤颤伴长R-R间期患者的24小时动态心电图进行分析和探讨其临床意义。方法:使用深圳博英十二通道Holter记录系统,对150例心房纤颤伴长R-R间期(≥1.5S)患者进行连续24小时的记录。结果:150例患者中R-R间期1.5--2.0S的97例,占全组的80%;R-R间期2.0-3.0s的38例,占全组的。R-R间期的>3.0S的30例,占全组的20%;伴交界区性逸博的130例,占全组的86.7%;心室率40次/min的40例,占全组的26.7%;室性期前收缩85例,占全组的56.7%。本组动态心电图检查过程中发生昏厥20例,由房颤演变成室颤的2例。长间歇发生多在午休、夜间卧床休息时间。结论:由于动态心电图可以24小时监测心电图的变化,所以房颤患者应尽早进行动态心电图的检查,特别是出现心房纤颤伴长R-R间期时,应予以相当的重视,以便及早做出诊断及干预,可以预防很多心房纤颤患者晕厥的发生。
Atrial fibrillation is one of the most common arrhythmia, it is more common in patients with organic heart disease, atrial fibrillation often associated with a longer RR interval (≥ 1.5S), due to slower heart rate at night, more prone to long-term , Endangering patient’s life, this article mainly analyzes and discusses the clinical significance of 24-hour Holter monitoring of atrial fibrillation patients with long RR interval. Objective: To analyze and discuss the clinical significance of 24-hour Holter monitoring of atrial fibrillation patients with long R-R interval. Methods: 150 consecutive cases of atrial fibrillation with long R-R interval (≥1.5S) were recorded in 24-hour continuous recording system using Shenzhen Boven twelve channel Holter recording system. Results: Of the 150 patients, 97 patients with R-R interval of 1.5-2.0S accounted for 80% of the whole group; 38 patients with R-R interval of 2.0-3.0s accounted for the whole group. RR interval of> 3.0S in 30 cases, accounting for 20% of the whole group; with borderline regional esophageal 130 cases, accounting for 86.7% of the whole group; 40 ventricular rate 40 / min, accounting for 26.7 %; Ventricular contraction in 85 cases, accounting for 56.7% of the whole group. This group of Holter examination occurred in 20 cases of syncope, evoked by atrial fibrillation in 2 cases of ventricular fibrillation. Long intermittent occurred in the lunch break, bed rest at night time. CONCLUSIONS: Because Holter monitors ECG changes over a 24-hour period, patients with atrial fibrillation should be examined for ambulatory electrocardiograms as soon as possible. In particular, considerable attention should be given to the presence of atrial fibrillation with long RR intervals for early diagnosis and Intervention can prevent the occurrence of syncope in many patients with atrial fibrillation.
