Abstract
Objective： To 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.Methods： Retrospective 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.Results： The 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）.Conclusion： 24 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.关键词
