Educational Pearls

• Atrial fibrillation is common.
• One of the best treatments for a fib is cardioversion back into sinus rhythm.
• Cardioversion may increase stroke risk if A-Fib duration is greater than 48 hours, but some new data suggests that this risk may happen as soon as 12 hours.
• However, newer studies show that cardioversion is generally safe as a treatment for A-Fib.
