Activity Helps Heart Rhythms
Atrial fibrillation (AFib) -- irregular heart rhythms -- can cause poor blood flow and lead to blood clots, which in turn raises the risk of stroke. AFib can be a fluttering, quivering heart rate, palpitations, thumping in the chest or even the skipping of beats. A new study suggests that staying active may help reduce the risk of developing AFib. In the study, women who walked briskly for at least 3 hours per week or did some equivalent form of exercise had a 10% lower risk of AFib than those who were sedentary. The risk was also higher in overweight and obese women than in normal-weight women. Women who were both obese and sedentary had a 44% greater risk.
