This document discusses the management of supraventricular tachycardias (SVT) beyond adenosine. It provides an overview of SVT pathophysiology, ECG features, and treatment options. Common SVT types include atrioventricular nodal reentrant tachycardia and accessory pathway mediated tachycardias. Adenosine is usually first line treatment but other drugs like amiodarone, sotolol, and calcium channel blockers may be used. Rarely, sodium channel blockers like procainamide are needed for refractory cases. The lecture highlights challenges in differentiating SVT from other rhythms and managing rare types. It also reviews ECG patterns in toxicity from drugs like
