Atrial fibrillation, commonly called A-fib, is an irregular and often rapid heart rate that can cause poor blood flow through the body. Symptoms of A-fib can include heart palpitations, shortness of breath, tiredness and weakness, but some people experience no symptoms at all. People who suffer from A-fib are at a greater risk for stroke.

Dr. Shane Rowan, a doctor from the CardioVascular Institute of North Colorado has been explaining A-fib to us, as part of the Passport to Health series.
