摘要
目的对动态心电图中长RR间期≥2000ms进行分析(房颤除外),并探讨其诊断和鉴别诊断,以提高诊断的正确性。方法回顾性分析5000例动态心电图中161例中长RR间期≥2000ms者,统计导致长间期的各类病因和心电图改变。结果长RR间期的总发生率为3.22%(161/5000),50岁以上患者占85.22%,病因以冠心病、心肌梗死、高血压病多见;导致长间期的心电图改变从高至低主要为房性早搏未下传27.33%(44/161),二度Ⅰ型房室阻滞14.29%(23/161),二度Ⅱ型窦房阻滞13.66%)22/161),窦性心动过缓伴不齐12.42%(20/161),三度房室阻滞6.83%(11/161)。结论动态心电图是长RR间期有效且安全的检测项目,熟悉导致长间期的病因、各类心电图改变之间的诊断和鉴别诊断有利于提高诊断正确率,有助于临床诊断和治疗。
Objective To analyzed the long RR intervals≥2000ms in ambulatory electrocardiograms（expect atrial fibrillation in full time） and discussed the diagnosis and differential diagnosis to improve diagnosis correctness. Methods We took retrospective analysis of 161 cases of which RR interval ≥2000ms in 5000 ambulatory electrocardiograms, and counted various types of pathogens of long RR intervals and their electrocardiogram changes. Results Patients over 50 years of age accounted for 85.22%, and common pathogens were coronary heart disease, myocardial infarction, high blood pressure. The occurrence of long RR intervals was 3.22%（161/5000）, the electrocardiogram changes which cause long intervals were ranged in descending order as blocked atrial premature beat 27.33%（44/161）, artrioventricular block（Mobitz type I）14.29%（23/161）, sinoatrial block （Mobitz type II）13.66% （22/161）, sinus bradycardia with sinus arrhythmia 12.42% （20/161）, complete artrioventricular block 6.83% （11/161）. Conclusions Ambulatory electrocardiogram is a secure and effective examination for long RR intervals, it was advantageous for improving diagnosis correctness and helpful to clinical diagnosis and treatment as we were familiar with the diagnosis and differential diagnosis between pathogens of long intervals and various types of electrocardiogram changes.
