Brisk walking pace and time spent at this speed may lower risk of heart rhythm abnormalities, research suggests
A brisk walking pace, and the amount of time spent at this speed, may lower the risk of heart rhythm abnormalities, such as atrial fibrillation, tachycardia (rapid heartbeat), and bradycardia (very slow heartbeat), finds ...
