Supraventricular tachycardia is an arrhythmia in heart disease, usually without organic cardiac manifestations. The main clinical features of supraventricular tachycardia are sudden onset and then abrupt cessation, with inconsistent duration, manifested by palpitations, anxiety, dizziness, and chest tightness. The severity of symptoms depends on the severity of the primary disease and the degree and duration of the rapid ventricular rate. The rapid ventricular rate during an attack may lead to the development of syncope. Treatment may include stimulation of the vagus nerve with the drugs adenosine and verapamil. In the event of supraventricular tachycardia, it is important to seek medical attention and, under the guidance of a medical professional, choose the most appropriate treatment based on the cause and symptoms to maximize quality of life.
