Question

Answer 1

increased vagal tone ,

Answer 2

Athletes usually have a slow heart rate. If your heart beat is regular, without dropping of beats, and the rate is not too low, e.g. less than 50 per minute, you might not have to worry about. If you have dizziness or palpitation, or if you have any doubt then check with a physician.  

Answer 3

I used to get that all the time and i went 2 the doctor's and they referred me the hospital eventually i had an E.C.G scan done and found out i had a heart murmur ( when your heart skips a beat every minute) you shuld go to the doctor and get it checked out dont worry though it may not be nything serious.
