High Prevalence Of Atrial Fibrillation Found Among Cross-Country Skiers

Next month, in the Norwegian town of Rena, 12, 000 elite cross-country skiers will line up for this year's Birkebeiner ski marathon, an annual endurance race which will take them through 54 kilometres of snow-covered countryside to the winter sports resort of Lillehammer.
