Abstract:
Objective To investigate the anti-arrhythmias mechanism of nardostachyos chinensis batal by intracardiac electrophysiologic study. Methods Intracardiac electrophysiologic study were performed in 40 supraventricular tachycardia(SVT)patients before and after oral nardostachys chinensis batal administraton,and the results were compared with 35 SVT patients or normal persons without nardostachys chineusis batal intake. Results The atrial effective,relative,functional refractory periods(AERP,ARRP,AFRP)and ventricular ERP(VERP)were significantly longer in nardostachyos chinensis batal administration group than control(AFRP(358 ± 76)ms vs.(256 ±69)ms;ARRP(365 ±74)ms vs.(287 ±55)ms;VERP(264 ± 36)ms vs.(213 ± 27)ms respectively);but the sinus and atrioventricular node function had no changes. Conclusions The anti-arrhythmia mechanism of nardostachyos chinensis batal were related to the prolonged cardiac refractory periods and the reduced cardiac excitability.
