A-Fib Awareness

Atrial fibrillation, also called a-fib, is an irregular heart rhythm and is a major cause of strokes. Having a-fib increases your stroke risk by 500 percent. In addition, a-fib can lead to heart failure, dementia, and even Alzheimer's disease.

This month, in honor of Atrial Fibrillation Awareness Month we spoke with Tri-County Heart Institute’s cardiologist, Dr. Nitza Alvarez, to find out how doctors detect a-fib in their patients.
