ISA P, Rodrigo; GONZALEZ A, Rolando; VERGARA S, Ismael y BAEZA L, Mariana. Paroxysmal tachycardia in a patient with a permanent form of junctional reciprocating tachycardia. Rev. méd. Chile [online]. 2004, vol.132, n.5, pp. 608-613. ISSN 0034-9887. http://dx.doi.org/10.4067/S0034-98872004000500011.
Junctional reciprocating tachycardia is an atrioventricular reentrant tachycardia whose anterograde conduction occurs via the His Purkinje and the retrograde conduction via an accessory pathway with slow conduction. The most common form is incessant tachycardia but a paroxysmal form also exists. We report a 35 years old female with recurrent paroxysmal tachycardia, that underwent electrophysiological evaluation. A left posterolateral accessory pathway was documented. Reciprocating paroxysmal tachycardia was induced by electrical stimulation and a successful pathway ablation was performed (Rev Méd Chile 2004; 132: 608-13).
