摘要:

[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。

Abstract:

[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.
