exercise-induced atrial flutter
Development of atrial flutter arrhythmia during or immediately following physical exercise.
Full Definition
Exercise-induced atrial flutter is a specific type of supraventricular arrhythmia that occurs during or shortly after physical exertion, characterized by rapid, regular atrial activity typically at rates of 250-350 beats per minute. In athletes, this condition may represent an exercise-triggered arrhythmia that could indicate underlying atrial substrate abnormalities or ion channel disorders. The condition requires careful evaluation as it may be associated with increased risk for other atrial arrhythmias and may impact athletic performance and safety during competition.
Usage
Usage note: Distinguish from atrial fibrillation by the regular nature of atrial activity and characteristic sawtooth pattern on ECG.
