high blood pressure
"I run regularly and have a resting heart rate in the low 50's.  I'm 56 years old and have been on metoprolol  for about 3 years until last week.  I also recently gave up caffeine. Last week I was sitting with a client and fainted.  After a trip to the ER and an overnight hospital stay, I learned it may not be a good idea for anyone who runs regularly with a low resting heart rate to take a beta blocker.  It could've have been a much more expensive lesson 20 minutes earlier while I was driving.  Now I am searching for the best BP medicine for runners.. Any suggestion would be appreciated."
