For example, increased vagal tone, which is often observed in the endurance athlete, has been shown to result in a short atrial RP, and thus initiates AF.355 Most studies have shown structural changes in endurance athletes, which have resulted in the term athlete’s heart. These changes include dilatation of all four heart chambers, increase in left ventricular mass, and mild right ventricular hypertrophy.356 Initially, these adaptive changes were felt to be benign; however, emerging evidence suggests otherwise, with endurance athletes experiencing higher-than-expected rates of coronary artery calcium scores, myocardial fibrosis, AF, and sinus node dysfunction.357","tracks":[{"project":"2_test","denotations":[{"id":"28506916-12057990-45814660","span":{"begin":325,"end":328},"obj":"12057990"},{"id":"28506916-12057990-45814660","span":{"begin":325,"end":328},"obj":"12057990"},{"id":"28506916-9890846-29307501","span":{"begin":579,"end":582},"obj":"9890846"},{"id":"28506916-9890846-29307501","span":{"begin":579,"end":582},"obj":"9890846"},{"id":"28506916-26607287-29307502","span":{"begin":839,"end":842},"obj":"26607287"},{"id":"28506916-26607287-29307502","span":{"begin":839,"end":842},"obj":"26607287"},{"id":"T69058","span":{"begin":325,"end":328},"obj":"12057990"},{"id":"T77197","span":{"begin":325,"end":328},"obj":"12057990"},{"id":"T61648","span":{"begin":579,"end":582},"obj":"9890846"},{"id":"T64151","span":{"begin":579,"end":582},"obj":"9890846"},{"id":"T51039","span":{"begin":839,"end":842},"obj":"26607287"},{"id":"T14030","span":{"begin":839,"end":842},"obj":"26607287"},{"id":"T46380","span":{"begin":325,"end":328},"obj":"12057990"},{"id":"T28593","span":{"begin":325,"end":328},"obj":"12057990"},{"id":"T33180","span":{"begin":579,"end":582},"obj":"9890846"},{"id":"T36897","span":{"begin":579,"end":582},"obj":"9890846"},{"id":"T61452","span":{"begin":839,"end":842},"obj":"26607287"},{"id":"T3486","span":{"begin":839,"end":842},"obj":"26607287"}],"attributes":[{"subj":"28506916-12057990-45814660","pred":"source","obj":"2_test"},{"subj":"28506916-12057990-45814660","pred":"source","obj":"2_test"},{"subj":"28506916-9890846-29307501","pred":"source","obj":"2_test"},{"subj":"28506916-9890846-29307501","pred":"source","obj":"2_test"},{"subj":"28506916-26607287-29307502","pred":"source","obj":"2_test"},{"subj":"28506916-26607287-29307502","pred":"source","obj":"2_test"},{"subj":"T69058","pred":"source","obj":"2_test"},{"subj":"T77197","pred":"source","obj":"2_test"},{"subj":"T61648","pred":"source","obj":"2_test"},{"subj":"T64151","pred":"source","obj":"2_test"},{"subj":"T51039","pred":"source","obj":"2_test"},{"subj":"T14030","pred":"source","obj":"2_test"},{"subj":"T46380","pred":"source","obj":"2_test"},{"subj":"T28593","pred":"source","obj":"2_test"},{"subj":"T33180","pred":"source","obj":"2_test"},{"subj":"T36897","pred":"source","obj":"2_test"},{"subj":"T61452","pred":"source","obj":"2_test"},{"subj":"T3486","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#93ecbb","default":true}]}]}}
