sir, I had taken aten-25 last October-10 for 15 days only, early in the morning. after that I feel my pulse comes down 48 from 84. I asked my doctor, he advised me to stop this medecine. now my pulse 55 when I wake up, after taking meals and going to office it gradually increase to 60 and 70 maximum. also I note that pulse is not regular, after 20 - 25 pulse the gap between 2 pulse increase upto 4-5 pulse than come down at starting level again. should I go to a doctor for this?
