My guest is Dr. Christopher DeSimone, a cardiologist and electrophysiologist at Mayo Clinic who diagnoses and treats people with atrial fibrillation (A-Fib). He says A-Fib is caused by electrical issues in the heart and treating it is sort of like caging a tiger. And he says the way exerts approach treatment is changing.

"There's new research that shows treating the bad rhythms and getting people back into a normal heart rhythm sooner is really beneficial," says DeSimone.

Treatment has been such that some people without symptoms could stay in a-fib for periods of time, as long as their heart rate stayed below a certain level. Watch as DeSimone discusses causes, symptoms and treatment options for A-Fib.
