[How to approach the patient with supraventricular tachycardia in the EP lab: A systematic overview].

The term supraventricular tachycardia (SVT) summarizes those tachycardias involving the atrial myocardium along with the atrioventricular (AV) node. The prevalence is about 2.25 per 1000 (without atrial fibrillation and atrial flutter) and, therefore, SVT represents one of the most common group of arrhythmias besides atrial fibrillation encountered in the emergency department especially since they tend to recur until definite therapy. The clinical symptoms may include palpitations, anxiety, presyncope, angina, and dyspnea. Pharmacological therapy of these arrhythmias often fails. The present article deals with the differential diagnosis of SVT and also introduces a series of manuscripts that provide detailed insight into the differential diagnosis and treatment of these arrhythmias.
