PELLIZZON, Oscar A  e  ELIZARI, Marcelo V. Trigeminia de la bigeminia ventricular por mecanismo reentrante: reentrada de la reentrada. Medicina (B. Aires) [online]. 2017, vol.77, n.6, pp.515-516. ISSN 0025-7680.

The process that follows an acute myocardial infarction generates an appropriate substrate for the formation of reentry circuits, considered to be the most frequent mechanism of ventricular extrasystoles and tachyarrhythmias. We present the case of a patient with an acute myocardial infarction unusually concurring with ventricular trigeminy coupled to ventricular bigeminated extrasystoles giving rise to a trigeminy sequence over the bigeminy, which indicates the existence of two reentry circuits (reentry of reentry) that trigger ventricular flutter.
