Differentiating wide complex tachycardias: A historical perspective

One of the most critical and challenging skills is distinction wide complex tachycardias into ventricular tachycardia or supraventricular tachycardia. Prompt accurate differentiation naturally influences short- long-term management decisions may directly affect patient outcomes. Currently, there are many useful electrocardiographic criteria algorithms designed to distinguish accurately; however, no single approach guarantees diagnostic certainty. In this review, we offer an in-depth analysis available methods differentiate by retrospectively examining its rich literature base – one that spans several decades.
