The optimal age for surgery for supraventricular tachycardia is currently inconclusive, with most hospitals capable of performing radiofrequency ablation of supraventricular tachycardia being able to do so at a minimum age of thirteen or fourteen, and for the highest age often reaching into the eighties. Patients are generally required to have good physical signs, no obvious infections, women who are not menstruating, and more frequent episodes. Because supraventricular tachycardia is generally not fatal, the pattern of episodes has changed from no episodes for several years to annual or frequent monthly or even daily episodes. The duration of the episodes also changes from a few seconds to a few minutes or even a few hours, or even a day or two. Since these patients have a tendency to have more frequent symptoms, they should be operated on as soon as possible, and because of this, cardiologists are now commonly recommending that patients undergo radiofrequency ablation when supraventricular tachycardia first occurs. Therefore, the optimal age for treatment of supraventricular tachycardia is as early as possible, and the procedure can be tolerated as long as the patient is in good general health and has no inflammation or infection.
