Supraventricular tachyarrhythmias. Mechanisms, types, and management.
Advances in the area of clinical electrophysiology have allowed definition of the mechanisms of most forms of supraventricular tachyarrhythmias. Reentry, automaticity, and triggered activity are the three basic mechanisms. Treatment of the arrhythmias is based on frequency and hemodynamic severity. After accurate diagnosis, empirical therapy with currently available medications usually controls symptomatic supraventricular tachyarrhythmias. Nonpharmacologic therapy with permanent antitachycardia pacemakers, percutaneous catheter ablation, or surgery is indicated for selected patients with medically recalcitrant supraventricular tachyarrhythmia.
