Why the study?
Does extreme endurance training increase the risk of sinus node disease and arrhythmias in former professional cyclists compared to age-matched controls?
Does extreme endurance training increase the risk of sinus node disease and arrhythmias in former professional cyclists compared to age-matched controls?
Former professional cyclists have a significantly higher risk of sinus node disease and a trend toward more frequent ventricular tachycardias compared to age-matched controls.
May support arrhythmia monitoring in former endurance athletes; hypothesis-generating for training-related sinus node disease.
Among FAs, SND occurred significantly more often compared with age-matched controls, and there is trend towards more frequent ventricular tachycardias. Further studies have to evaluate prevention of arrhythmias with extreme endurance training, the necessity of regular follow-up of heart rhythm, and management of arrhythmias in former competitive endurance athletes.
