I'm 21 and have atrial fibrillation, what can i do?

Cardiologist : You should really see a cardiologist who can go over all of the options with you and well as work out any possible underlying causes such as elevated thyroid. You need to carefully discuss whether it is best to try and keep you out of afib with a procedure or medications or not. This is a long discussion that needs to be tailored to the individual.
