Coffee won't make your heart flutter, study says

There's increasing evidence that coffee could be healthier:

> In fact, a habitual coffee habit was associated with a lower risk of developing an arrhythmia, such as atrial fibrillation in which the heart races, or flutters in the chest, the study found.

> The study, published Monday in JAMA Internal Medicine, analyzed coffee consumption by more than 386,000 people over a three-year period and compared that with rates of cardiac arrhythmia, which might include atrial fibrillation.

> The notion that coffee causes the heart to flutter was born from older, small studies, including one that focused entirely on male physicians, wrote Marcus and his team from the University of California San Francisco.
