Tachyarrhythmias in young athletes
Journal of the American College of Cardiology
|January 1, 1986
Summary
Young athletes can experience various tachyarrhythmias, often linked to underlying heart conditions. These arrhythmias frequently occur during strenuous exercise, highlighting the importance of thorough cardiac evaluation.
Area of Science:
- Cardiology
- Sports Medicine
- Electrophysiology
Background:
- Symptomatic tachyarrhythmia in young athletes is a concern.
- Understanding the triggers and substrates is crucial for management.
Purpose of the Study:
- To systematically evaluate young athletes with symptomatic tachyarrhythmia.
- To identify underlying causes and exercise-related triggers.
Main Methods:
- Systematic evaluation of 19 young athletes with documented tachyarrhythmia.
- Assessment included medical history, physical examination, and electrophysiological studies.
- Cardiac imaging and exercise testing were utilized.
Main Results:
- Common tachyarrhythmias included paroxysmal atrial fibrillation, supraventricular tachycardia, and ventricular tachycardia.
- Abnormal substrates, such as anomalous atrioventricular pathways and heart disease, were found in 79% of athletes.
- Tachyarrhythmias were frequently triggered by strenuous exercise (68%) and induced by programmed stimulation (68%) or exercise testing (42%).
Conclusions:
- Young athletes can present with diverse tachyarrhythmias.
- A significant proportion have identifiable abnormal cardiac substrates.
- Exercise is a frequent trigger for tachyarrhythmia events in this population.
