Abstract：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.
