Atrial fibrillation, also known as AFib, happens when your normal heartbeat or rhythm is thrown off. Yes, it can be dangerous. Your heart may not be able to pump enough blood.
On the other hand, millions of people with long-lasting AFib live quite well, says Gordon F. Tomaselli, MD, chief of the division of cardiology at Johns Hopkins University School of Medicine. "It's very possible to live a normal life for many years."
So let's clear up those ideas that may be limiting you when they don't...
It's possible that you have problems that need treatment first. Your cardiologist may suggest a cardiac rehabilitation program. Rehab specialists develop a custom exercise program with you, look out for any problems, and help you figure out when it's safe to push yourself.
After you get the OK from your doctor, these tips will help keep you exercising safely. Also check with your doctor to see if there are other specific things you need to know or watch out for.
Build Up Gradually
When you have AFib, jumping into exercise too quickly -- with high intensity or long workouts -- could cause symptoms. Instead, start slowly with 5 to 10 minutes a day of walking. Add a minute or two every week or so.
Your ultimate goal is a total of 30 minutes of activity a day, 5 days a week. You want to boost your heart rate, breathe a little faster, and sweat a bit for a good workout.
Check Your Pulse
Ask your doctor what your heart rate should be while you're exercising and after you've cooled down.
Get his advice on what to do if your pulse is too low: Should you exercise longer, or push yourself harder?
If your pulse is too high, you're more likely to have symptoms. Find out what to do to bring it down.
Watch for Symptoms
When exercise causes pain, extreme breathlessness, or exhaustion, stop. Talk to your doctor before you work out again. You may need tests to make sure you don't have a new problem.
"Aside from the heart benefits, once you add exercise into your life, you'll really feel better," says Gordon Tomaselli, MD, chief of cardiology at Johns Hopkins University School of Medicine. "Regular exercise helps people get more out of life."
