摘　　要：目的了解药物治疗左心室假腱索所致室性早搏的方法。方法选取近两年来51例室性早搏患者为研究对象,均排除器质性心脏病。心超检查示左心室假腱索,心电图及动态心电图提示频发室性早搏。给予口服盐酸美西律、酒石酸美托洛尔联用治疗。结果所有患者经治疗后早搏次数均有不同程度减少,早搏发生率较服药前降低。结论盐酸美西律、酒石酸美托洛尔片联合应用治疗左心室假腱索所致室性早搏效果显著。Objective To know the drug therapy for premature ventricular beat( PVB) caused by left ventricular false chordae tendineae( LVFCT).Methods Fifty-one patients diagnosed with PVB for the past two years were enrolled in our study.The possibility of organic heart disease was excluded.Echocardiographic examination indicated LVFCT while electrocardiogram and ambulatory electrocardiography inspections revealed frequent PVB.The combination of Mexiletine Hydrochloride and metoprolol tartrate tablets was taken by the patients following oral administration.Results After the drug therapy,the frequency of premature beats and the incidence of PVB all decreased for all the enrolled case.Conclusion The therapeutic effect of the combination of Mexiletine Hydrochloride and metoprolol tartrate tablets proves to be more remarkable in treating PVB caused by LVFCT.
