目的:前瞻性观察右心室单腔起搏器睡眠频率功能开放对左心房的影响及可能机制.方法:30例Ⅲ度房室传导阻滞患者成功置入永久单腔心脏起搏器,随机分为睡眠功能开放组及未开放,分别在植入后出院前、1年、2年时随访时,测定右室起搏比率,24h总心搏数及心房颤动(AF)发生率,左心房内径(LAD).结果:两组的右室起搏比率比较、在刚植入时24h总心搏数比较和AF发生率比较,差异无统计学意义(P>0.05);1年及2年时总心搏数比较、AF发生率比较差异有统计学意义(P<0.05);LAD变化:开放组差异无统计学意义(P>0.05),对照组差异有统计学意义(P<0.05).结论:睡眠频率功能开放可减少右室起搏数量,延缓左心房扩大,减少AF的发生.
목적:전첨성관찰우심실단강기박기수면빈솔공능개방대좌심방적영향급가능궤제.방법:30례Ⅲ도방실전도조체환자성공치입영구단강심장기박기,수궤분위수면공능개방조급미개방,분별재식입후출원전、1년、2년시수방시,측정우실기박비솔,24h총심박수급심방전동(AF)발생솔,좌심방내경(LAD).결과:량조적우실기박비솔비교、재강식입시24h총심박수비교화AF발생솔비교,차이무통계학의의(P>0.05);1년급2년시총심박수비교、AF발생솔비교차이유통계학의의(P<0.05);LAD변화:개방조차이무통계학의의(P>0.05),대조조차이유통계학의의(P<0.05).결론:수면빈솔공능개방가감소우실기박수량,연완좌심방확대,감소AF적발생.
@@@@Objective:Prospective observational and possible mechanisms of right ventricular single chamber pacemaker sleep function and opening of the left atrium. Methods:30 casesⅢdegree atrioventricular block patients successfully implanted permanent single-chamber pacemakers, were randomly divided into the sleep function open group and not open, respectively, in 1 year, 2 years after implantation, before discharge, follow-up, measuredratio, the 24h total cardiac and atrial fibrillation (AF) incidence of right ventricular pacing, left atrial diameter (LAD). Results:Two groups of right ventricular pacing ratio compared to the just implantation 24h total cardiac compare and AF incidence, the difference was not statistically significant (P>0.05);the total cardiac comparing 1 year and 2 years, The AF incidence difference was statistically significant(P<0.05). LAD change:open group, the difference has not statistically significant (P>0.05), and the control group, the difference was statistically significant(P<0.05). Conclusions:Sleep frequency function and opening up can reduce the number of right ventricular pacing, slow left atrial enlargement, and to reduce the occurrence of AF.
