Most patients do not experience any discomfort after surgery. Of course, the exception is when complications occur. However, some patients may still have some uncomfortable manifestations such as heartburn and chest tightness. These uncomfortable manifestations do not require special attention after excluding complications, because, after all, the surgery is performed inside the heart and some damage is done (without damage, the extra access cannot be completely cut off!). . So, inevitably, there will be some heart discomfort. However, most of these uncomfortable symptoms can disappear completely in 1-2 weeks after surgery and do not require special treatment. In general, antiplatelet drugs (usually aspirin) are required for 2-4 weeks after supraventricular tachycardia or preexcitation radiofrequency ablation. Other drugs vary depending on the underlying disease, and generally no further antiarrhythmic drugs are required after surgery (except for beta-blockers used to control other problems such as blood pressure). For patients who have tachycardia, they need to be monitored for tachycardia after surgery. If there is a feeling of tachycardia, it is recommended to have an electrocardiogram done nearby to clarify what kind of tachycardia is present. Not all episodes of tachycardia are paroxysmal supraventricular tachycardia, because other manifestations of tachycardia, such as sinus tachycardia, often occur in normal people! In general, if a recurrence occurs after surgery, it should occur relatively quickly, usually within 1-6 months. In contrast, there are very few patients who recur after 6 months. For patients with frequent episodes, recurrence is usually seen 2-3 months after surgery, while for patients with fewer episodes, the treatment can be extended to 6 months later. For patients without tachycardia but only preexcitation, postoperative observation of the recovery of preexcitation is required, which can be observed by a general electrocardiogram. Likewise, if there is a postoperative recurrence, it should occur relatively quickly, usually within 1-6 months. In contrast, few patients relapse after 6 months. Therefore, for patients with pre-excitation syndrome only, it is recommended to review the ECG at 2 weeks, 1 month, or 3 months after surgery to see if there is a recurrence. Of course, a longer period of time to check the ECG is also possible. In addition, we would like to remind our patients that the results of RF ablation for supraventricular tachycardia and preexcitation are very clear, although we do not say 100% success before the procedure, but the actual success rate of supraventricular tachycardia or preexcitation is close to 100% (our center’s experience), that is, there are very few supraventricular tachycardia or preexcitation that cannot be done. Moreover, RF ablation is a radical procedure, and if you do it well, you can get rid of the disease, and if you succeed, so to speak, you can look at yourself as if you never had the disease.
