Recommendations:
1. Athletes without structural heart disease, without a history of palpitations, or without tachycardia (particularly those 20 to 25 years old or more) can
participate in all competitive sports. However, in younger age groups, a more in-depth evaluation including an electrophysiologic study may be ecommended before allowing participation in moderateto high-intensity competitive sports.
2. Athletes with episodes of AV reciprocating tachycardia should be treated as previously recommended (see section on Supraventricular Tachycardia). However, it should be appreciated that they can develop atrial fibrillation with rapid ventricular rates. Electrical induction of atrial fibrillation to determine the shortest QRS interval between two complexes conducted over the accessory pathway during isoproterenol administration or exercise is recommended. Those athletes in whom the shortest cycle length is less than
250 ms should undergo ablation of the accessory pathway.
3. Athletes with episodes of atrial flutter/fibrillation and syncope or near syncope whose maximal ventricular rate at rest (without therapy) as a result of conduction over the accessory pathway exceeding 240 beats/min should be considered for catheter ablation therapy of the accessory pathway prior to continuing competition. Those whose ventricular rate during isoproterenol administration is less than 240 beats/min and who have no episodes of yncope or near syncope appear to be at low risk for sudden cardiac
death.
4. Athletes with no structural heart disease who have had successful catheter or surgical ablation of the accessory pathway, are asymptomatic, and have normal AV conduction and no inducible arrhythmia by follow-up electrophysiologic study can participate in all competitive sports in several days. Those without an electrophysiologic study and no spontaneous recurrence of tachycardia for two to four weeks after ablation can participate in all competitive sports.
