Does radiofrequency ablation require hospitalization? In most cases, hospitalization is required. The length of hospital stay varies depending on the type of arrhythmia, like supraventricular tachycardia, which is shorter, two or three days. Atrial fibrillation may take longer, about a week. What is the approximate cost of radiofrequency ablation? For different types of tachyarrhythmias, the cost of the procedure varies depending on the method of calibration, the number and type of calibration catheters and ablation catheters used. The simplest is the common type of supraventricular tachycardia, and the cost of the procedure is around$30,000 for the simplest and most commonly used labeling and ablation catheters, using two-dimensional labeling. For idiopathic ventricular premature and ventricular tachycardia, ablation can sometimes be attempted with a single catheter approach, and the procedure costs only about$20,000. For atrial flutter, atrial fibrillation, atrial tachycardia and ventricular tachycardia, the cost may range from$40,000 to$70,000 using a three-dimensional calibrated test and special ablation catheter. What should patients be aware of in their daily care after radiofrequency ablation? All patients need to lie flat and apply compression to the puncture site to stop the bleeding after the procedure. The duration of lying flat and compression varies depending on the site of the puncture and whether or not the arterial puncture is performed. It is not that the patient should not move at all when lying down and compressing to stop bleeding, but mainly the joints at the puncture site should be braked. For patients with supraventricular tachycardia, aspirin is given for about one month after radiofrequency ablation, after which life is completely normal. Atrial fibrillation ablation is followed by two to three months of treatment with anticoagulants. If AF does not recur thereafter and the patient is at low risk for thromboembolism, anticoagulation can be discontinued. If the patient also has coexisting underlying heart disease, he or she should be maintained on medication for the underlying heart disease. It is important to remind patients and family members to strengthen disease self-management and disease awareness, regardless of the type of arrhythmia. It is important for the diagnosis of arrhythmia if the patient and family can provide the mode of onset, symptoms, duration, how fast the heartbeat is, whether the pulse is aligned or not and the factors affecting it, etc. The diagnosis can be confirmed if there is evidence of ECG during the attack. In outpatient clinics, we often encounter patients who are not able to say, some of them say they have panic attacks, and they cannot answer whether the panic attacks are slowly getting better or suddenly getting better, how long they last and so on. Therefore, whether it is the first visit or postoperative follow-up, patients and family members should record some characteristics related to the onset of the disease. This is especially true for episodes of disease, which will facilitate the physician’s judgment of the patient’s condition and the correct diagnosis of the arrhythmia. Approximately how long can a patient be hospitalized after seeing an outpatient clinic? For relatively simple arrhythmias like supraventricular tachycardia, the procedure is quicker, many units can be scheduled in a day, and the patient’s waiting time is shorter. Depending on the bed and procedure schedule, the patient can be hospitalized immediately or within a few days. In most cases, it takes about two to three weeks from the time a patient is registered to the time he or she is admitted to the hospital. In case of holidays, the waiting time may be longer. Some patients may require preoperative anticoagulation therapy. Ablation is generally feasible after 3 weeks on warfarin at therapeutic intensity (INR between 2-3), or 3 weeks on a new oral anticoagulant prior to surgery.
