摘要/Abstract

摘要： 目的对动态心电图中长R－R间期(房颤除外)进行临床分析，并探讨其产生的原因及临床意义。方法回顾性分析2009年6月－2011年6月间2500例动态心电图中65例R－R间期延长者(且R－R间期均﹥2.0s为标准)，统计导致长间歇的各类病因和心电图改变。结果长R－R间期的总发生率为2.60％(65／2500)，50岁以上者占92.30％(60／65)。病因以冠心病、高血压多见。导致长间歇的心电图改变从高到低依次为窦性停搏43.08％(28／65)，房性早搏未下传20.00％(13／65)，二度Ⅱ型房室传导阻滞18.46％(12／65)，二度I型房室传导阻滞10.77％(7／65)，二度窦房传导阻滞3.08％(2／65)，房速后代偿3.08％(2／65)，三度房室传导阻滞1.54％(1／65)。结论24小时动态心电图是长R－R间期检测的既有效又安全的方法。认识导致长R－R间期发病的病因，以及了解引起各类心电图改变的原因，对临床工作有重大的意义。

Abstract: ObjectiveTo analyze long R－R intervals in ambulatory electrocardiography (AECG) (expect atrial fibrillation in full time), and to probe into the significance of clinical and the cause of long interval. MethodsRetrospective analysis of 65 cases of R－R interval ≥2.0 s in 2 500 AECGs from the June 2009 to the June 2011 was made, and various types of pathogens of long R－R intervals and their electrocardiogram changes were collected. ResultsThe occurrence of long R－R intervals was 2.60 ％(65／2 500). Patients over 50 years old accounted for 92.30％(60／65), and common pathogens were coronary heart disease, high blood pressure. The electrocardiogram changes which cause long intervals were ranged in descending order as sinus arrest 43.08％(28／65),blocked premature atrial contraction 20.00 ％(13／65), artrioventricular block (Mobitz typeⅡ) 18.46 ％(12／65), artrioventricular block(Mobitz typeⅠ) 10.77 ％(7／65),sinoatrial block 3.08％(2／65),compensatory pause after atrial tachycardia 3.08 ％(2／65),complete artrioventricular block 1.53 ％(1／65). Conclusion24 hours AECG is a secure and effective examination for long R－R intervals. The pathogens of long intervals and various types of electrocardiogram changes have been found out, which is significant for clinical job.
