Bradycardia: Concern?

I am a 26 year old female who exercises regularly 3-4 times a week for 20-30 minutes. I recently went to the doctor for a check up and happened to mention I get dizzy with exercise. He hooked me to an EKG and noticed my resting heart rate was 45. He referred me to a cardiologist and I wore a 24 hour holter monitor that determined I have sinus bradycardia and sinus arrythmia. I am supposed to see the cardiologist again in 3 months.

Since my visit with the doctor and I really worried because I never expected to have any heart issues. I am tired all of the time ( I figured due to everyday life) and I feel lightheaded although I have never fainted. I am afraid to do strenuous exercise because I don't want to pass out! I am not sure if this is all in my imagination or I am actually having these symptoms.

Should I be worried? Any other healthy females out there with the same issue?

You don't have any heart issues! Both brady and sinus arrhythmia is a sign of a healthy heart in young men and women. As long as the rate increases with exercise there's no need to worry!:) Unless your cardiologist knows something yoy don't mention here.

Thank you for the reply! I know I am a healthy individual, but the only thing that bothers me is the dizziness. There are some days I feel like I am about to pass out. Is this something I am just supposed to deal with going forward? I don't want to seem like I am trying to find something wrong, just want to know what causes this.

Try to check BP and heart rate when feeling dizzy. If it is too low, that's the explaination. Or in rare cases too high. if not, the cause is not cardiovascular. Maybe you have tense muscles?

Hmmm, who knows. I go back to see the cardiologist in a few months. I guess if I don't pass out then I am fine!

try drinking cold water when you exercise and keep hydrated well enough to see if this helps.. if you don't already; it may be helpful to keep track of how much water you're drinking daily and how much you intake while exercising;

sometimes it can be as simple as adding an extra glass of water to your routine; other times there may be a imbalance in electrolytes or hormones etc that may or may not balance back out...

keep a journal/log of dates times symptoms and what you were doing at the time to see if you find a pattern and I would def ask about the stress test since you've had dizziness while exercising

Thank you! The doctor did tell me to increase my water intake and also to try gatorade. I hope it helps. I have read about healthy women having heart problems so I just want to be proactive to make sure I am not one of them! :)
