The treatment of paroxysmal atrial tachycardia mainly includes general treatment, physical therapy, drug therapy, electrical cardioversion, catheter ablation therapy. 1. General treatment: If there is no cause, reduce activities, keep emotional stability, and wait for the heart rate to recover by itself. If there are clear triggers, such as coronary heart disease, heart failure, myocardial infarction, hypoxia, electrolyte disorders, drug poisoning and other diseases, we need to focus on the underlying causes and triggers of treatment. 2. Physical therapy: use of methods to stimulate the vagus nerve, such as the Valsalva maneuver, cough, vomit reflex, pressure on the eyeballs and massage of the carotid sinus. Pressure and massage should not be applied to both sides at the same time, and the action should be gentle, and this method should be used with caution for the elderly. 3. Drug therapy: drugs commonly used to relieve the condition include adenosine triphosphate, verapamil, propafenone, quinidine, procainamide, propylamine, amiodarone and so on. 4. Electric cardioversion: If drug treatment is ineffective or the patient has hemodynamic changes such as blood pressure drop and heart failure, synchronous direct current cardioversion and esophageal pacing cardioversion can be chosen. 5. Catheter ablation therapy: through the application of high-energy current, laser, radiofrequency current, cytotoxic substances, freezing and ultrasound, etc., the focal area of myocardial necrosis, to achieve the purpose of treating paroxysmal atrial tachycardia. If the symptoms of paroxysmal atrial tachycardia are not relieved or are accompanied by other symptoms, you should go to the hospital in time and give targeted treatment after clarifying the cause with the help of doctors.
