Objective: To evaluate the therapeutic effect of Yangxin Fumai Oral Liquid (YFOL,养心复脉口服液), a Chinese herbal medicine for nourishing Heart and restoring pulse, in treating patients with extrasystole. Methods: The effect of YFOL was observed in treating 30 patients with different kinds of extrasystole and compared with that in 30 patients treated by propafenone. The effect of YFOL on experimental arrhythmia was studied in animals as well. Results: Clinical observation showed that the effect of treatment against extrasystole in the two groups was similar, but the YFOL group showed better results in symptom improvement (P<0.01) with no marked side-effect. Experimental study showed that YFOL could reduce the chloroform induced ventricular fibrillation occurrence in mice, delay the initiating time of ventricular extrasystole, tachycardia and fibrillation induced by aconitine, BaCl2 and coronary artery ligation in rats, or shorten the lasting time of arrhythmia, reduce the attacking frequency of ventricular extrasystole. There was significant difference in comparing with the control group (P<0.05, P<0.01). Conclusion:YFOL is a good and convenient Chinese herbal preparation for different kinds of extrasystole with few toxic and side-effect in clinical practice.
