Our results showed that the serum digoxin concentration reached peak value 1h after taking digoxin at 7: 00 a. m.,but the serum digoxin concentration reached the peak value 2 h after taking digoxin at 4: 00 p. m.. The average serum digoxin concentration area under curve was greater and the best maintainable time of serum concentration within 24 h after taking digoxin at 4 p. m. longer than those at 7: 00 a. m.. The heart rates were obviously lower and the cardiac function was significantly improved in 4:00 p. m.group.展开更多
