For patients with paroxysmal supraventricular tachycardia, termination of the attack and prevention of recurrence is the key, in the phase of termination of the attack, the first choice of drugs such as lidocaine or procainamide, and the prevention of recurrence needs to be the cause of the treatment, and when the above treatments are ineffective, surgical treatment can be given, and the first choice of catheterized radiofrequency ablation and eradication. 1. Termination of episodes: If the patient is not hemodynamically impaired, firstly, lidocaine or procainamide can be used for static injection, and at the same time, a continuous drip, but patients with confirmed heart failure should be cautious; in addition, it can also be supplemented with compression of the eyeballs, breath-holding, etc. to terminate the episodes of supraventricular tachycardia through the stimulation of the vagus nerve. 2. Prevention of recurrence: We should actively cooperate with doctors to implement interventional therapy in combination with the causes and triggers of the disease. For common causes such as low blood potassium, aspirin and potassium chloride can be given. 3. Surgery: Catheterized radiofrequency ablation is preferred for eradication, which is a minimally invasive procedure that involves placing a catheter into the heart and then introducing electric current for ablation to restore the normal rhythm of the heart. For people at high risk of supraventricular tachycardia, they should be highly vigilant and seek medical attention as soon as they feel unwell, and choose the best treatment under the guidance of their doctors.
