Supraventricular tachycardia or pre-excitation is a relatively common arrhythmia with a very clear pathogenesis, and it can be treated by catheter ablation to achieve a cure. However, after answering patient inquiries on the Internet for some time, I have found that many patients have many questions about whether supraventricular tachycardia (pre-excitation) can be treated well; there are also many patients on the Internet who have more concerns about the treatment of this disease because of postoperative recurrence; in addition, some patients have many concerns about the management of their disease because of the unsuccessful experiences of other patients; the list goes on and on. Therefore, I would like to combine my years of experience in the treatment of supraventricular tachycardia or pre-excitation and hope that this article will help to clear the doubts of many patients concerned and help to establish confidence in the complete resolution of supraventricular tachycardia or pre-excitation and the correct treatment of the disease. The question of whether supraventricular tachycardia or pre-excitation will improve and be cured needs to be looked at from different perspectives. If one is hoping that the supraventricular tachycardia or pre-excitation will cure or get better on its own, then this approach is basically impossible. Supraventricular tachycardia or prodromal excitation occurs when the heart develops an abnormal conduction pathway (one or more) in addition to the normal conduction pathway (atrioventricular node). Generally speaking, except for infants and children with preexcitation, most patients are unlikely to recover spontaneously after an episode of supraventricular tachycardia, but will have a natural course of more frequent episodes (shorter intervals between episodes) and longer episodes (see the related article: Frequently Asked Questions about supraventricular tachycardia (including preexcitation)). If it is hoped that supraventricular tachycardia or preexcitation can be cured by medication, this is also largely unachievable. In general, pharmacological treatment is effective in terminating supraventricular tachycardia, but it is difficult to remove the preexcitation. If preexcitation is to be removed from the ECG, then a significant drug dose is required to have a small chance of temporarily removing preexcitation, and treatment with large doses of drugs is likely to have many side effects and is therefore not recommended. And medications used to prevent episodes of supraventricular tachycardia are very ineffective. It is possible that when medication is first started, many patients may experience fewer episodes and shorter durations; they may think they are “cured” of the problem. But this is actually an illusion, because drugs do not solve the underlying problem! After a period of time, the previously effective medications will gradually fail and the episodes of supraventricular tachycardia will recur, and if no effective intervention is made, the patient is likely to re-enter its natural course and may develop other complications, such as tachycardic cardiomyopathy and hypocardia. If the hope is that supraventricular tachycardia or pre-excitation can be cured surgically, then this is the right choice and is currently the most effective approach. The pathogenesis of supraventricular tachycardia or pre-excitation is very clear: it is caused by the presence of one or more abnormal conduction pathways in the heart. These conduction pathways are histologically myocardial cells (not blood vessels, mind you) that cause the disease to develop simply by being in places where they should not be. By applying ablative energy to these abnormal conduction pathways through the catheter, these abnormal conduction pathways (myocardium) become necrotic and lose their conduction (conductive) function, and then the supraventricular tachycardia or pre-excitation loses its fundamental basis for arrhythmia and is therefore completely cured. After many years of clinical practice, even the most abnormal pathways can be completely cured by careful identification and delicate operation of the operator. Therefore, to summarize the above, the answer to the title of this article is clear: supraventricular tachycardia or preexcitation will be fine, but a correct approach needs to be chosen.
