A new study found that smoking may raise your risk of developing a type of heart rhythm disorder.

Researchers tracked the health records of over 15,000 middle-aged people. Those who smoked were twice as likely to develop atrial fibrillation compared to those who didn't smoke.

Even smokers who quit had a higher chance of getting the disorder.

Experts say atrial fibrillation can decrease your quality of life and increase your risk of stroke.
