摘　　要：目的探讨室性心动过速(室速)室房传导的关系。方法选取2010年1月—2012年9月因心动过速发作来我院行食管电生理检查(TEAP)并确诊为室速的患者67例,分析患者室房传导的关系。结果房室分离39例(58.2%);室房逆传28例(41.8%),其中:1∶1传导16例(23.9%)、2∶1传导7例(10.4%)、文氏型传导5例(7.5%)。房室分离组与室房逆传组的年龄、性别构成、心脏基础疾病构成及心室率比较,差异均无统计学意义(P>0.05);房室分离组心室率≥200次/min患者的检出率较室房逆传组增多〔12例(30.8%)与2例(6.9%)〕,差异有统计学意义(P<0.05)。结论室速时可见房室分离及室房逆传;心室率≥200次/min时易出现房室分离现象。Objective To study the ventriculoatrial conduction relationship in patients with ventricular tachycardia （VT） . Methods 67 patients confirmed with VT and treated with TEAP in our hospital due to taehycardia from January 2010 to September 2012 were selected. The ventriculoatrial conduction relationship was analyzed. Results There were 39 cases of atrio- ventricular separation （58.2%）, 28 cases of atrioventricular reverse transmission （41.8%） . Among them, the there were 16 cases of 1：1 conduction （23.9%）, 7 cases of 2：1 conduction （ 10.4% ） and 5 cases of venturi type conduction （7.5%）. The age, gender composition, heart diseases and ventricular rate between the atrioventricular separation group and atrioventricu- lar reverse transmission group showed no statistically significant difference （P 〉 0. 05 ） . Compared with atrioventricular reverse transmission group, the atrioventricular separation group had significantly more patients with heart rate of 200 times/min [ 12 （ 30. 8% ） vs. 2 （ 6. 9% ） 3 （ P 〈 0. 05 ） . Conclusion Atrioventricular seperation and atrioventricular reverse transmission could be observed in VT. The atrioventricular seperation is likely to happen when the heart rate of a patient with VT is over 200 times/min.
