Nicotinamide 30 mM produced marked positive chronotropic effects with the sinus cycle length shortened by 65+/-9 ms (P<0.05), the rate of action potential phase 4 depolarization speeded up by 9.9+/-1.6 mV/s and phase 4 depolarization slope increased by 10 degree9’+/-2 degree6’ (P<0.05). It suggests that nicotinamide act as a positive chronotropic drug.Read More
