This story first appeared on Boxing Junkie , a USA Today Sports property. Roberto Duran was receiving treatment for a heart issue Saturday in his native Panama, The Associated Press reports. The 72-year-old Hall of Famer’s family stated on his Instagram account that he has an atrioventricular block, which, according to Yale Medicine, “is a heart rhythm disorder that causes the heart to beat more slowly than it should.” The Yale website went on: “It’s caused by communication problems within the heart’s electrical conduction system. For some people, the condition doesn’t cause symptoms; for others, it may be life-threatening.” Duran’s family was anticipating more news. “We are waiting for results so that we can provide more information on his health,” the family said
