左室假腱索与室性期前收缩的关系研究

目的]探讨左心室假腱索与室性期前收缩的关系。方法]选择超声心动图检出的左心室假腱索(LVFT)的健康人60例(左室假腱索组),随机选取无左心室假腱索的健康体检者60例(对照组),所有病例均行24 h动态心电图记录,分析比较两组室性期前收缩的发生率。结果]左室假腱索组60例中有45例发生室早,发生率为75%,对照组60例中12例发生室早,发生率为20%,两组比较差异有显著性意义(P<0.05)。而45例发生室早的假腱索中,横型的左室假腱索者30例,发生率为66.7%,纵型的左室假腱索者15例,发生率为33.3%,两组比较差异有显著性意义(P<0.05)。结论]左室假腱索是健康人室早的独立危险因素,左室假腱索横型者室早发生率较纵型者高。

Relationship between left ventricular false tendons and ventricular premature beats

Objective]To investigate the relationship between left ventricular false tendons(LVFT) and premature ventricular systolic(PVS).Methods]In LVFT group 60 healthy cases and randomized 60 cases of healthy people without LVFT in control group,screened by echocardiography were studied.All patients were recorded for 24 h dynamic eletrocardiogram.PVS was statistically analyzed between LVFT and control groups.Results]In LVFT group 45 cases of all 60 cases had PVS,with 75% as PVS incidence.In control group 12 cases of all 60 cases had PVS(20% PVS incidence).There was significant difference about the incidence of PVS between LVFT and control groups(P<0.05).Thirty cases of all 45 cases whose had PVS was horizontal type in LVFT group with incidence 66.7%.Among 45 cases in LVFT group,15 of them had PVS that was vertical type and the incidence was 33.3%.There was significant difference about the incidence of PVS between vertical type and horizontal type in LVFT group.Conclusion]LVFT was an independent risk for PVS of healthy people.The incidence of horizontal type in LVFT group was higher than the vertical type.
