Resumen

ASENJO, René et al. Wide QRS tachycardia: a diagnostic challenge. Rev Chil Cardiol [online]. 2020, vol.39, n.1, pp.55-65.  Epub 01-Abr-2020. ISSN 0718-8560.  http://dx.doi.org/10.4067/S0718-85602020000100055.

The correct electrocardiographic diagnosis of the cause of a wide QRS complex tachycardia (WCT) is essential since both management and prognosis of the patient.

The correct electrocardiographic diagnosis of the cause of a wide QRS complex tachycardia (WCT) is essential since both management and prognosis is different according to its etiology and defines the study that we should perform.

Numerous criteria and algorithms have been described to differentiate the origin of these tachycardias. However, many of these are complex and difficult to apply to the less experienced doctor. This is particularly important in emergency rooms, where a rapid definition is needed to allow proper therapy. In this review we analyze the different mechanisms of WCT and the main EKG diagnostic criteria, emphasizing those which can be applied rapidly and have high diagnostic value.

Palabras clave : Wide QRS complex tachycardia; Ventricular tachycardia; Supraventricular tachycardia with aberrant conduction; preexcited tachycardia.
