The proper management of supraventricular tachycardia includes vagus nerve stimulation, medication, electrical cardioversion, and catheter-based radiofrequency ablation therapy.
In patients with supraventricular tachycardia, if cardiac function and blood pressure are normal, attempts to stimulate the vagus nerve, such as carotid sinus massage, pharyngeal stimulation to induce nausea, and immersion of the face in iced water, may result in termination of the tachycardia.
Pharmacologic treatment of supraventricular tachycardia is preferred to adenosine, which has a relatively rapid onset of action. When adenosine is ineffective, drugs such as verapamil and propafenone may be used.
When supraventricular tachycardia drug treatment is ineffective, and at the same time, the patient has low blood pressure, congestive heart failure and other manifestations, direct current resuscitation therapy can be carried out.
Catheter radiofrequency ablation can cause specific local myocardial tissue degeneration and necrosis, and change the local myocardial autoregulation and conduction to achieve the therapeutic purpose, which is suitable for the treatment of supraventricular tachycardia.
When supraventricular tachycardia occurs, it is recommended to consult a doctor in time, and the medication should be used under the guidance of a professional doctor.
