We report the case of a 64-year-old woman who was admitted for cardiogenic shock caused by a permanent junctional reciprocating tachycardia. If this incessant and drug-refractory form of tachycardia is a well-known cause of tachycardia-induced cardiomyopathies in infants, its occurrence during adulthood is extremely rare. Catheter ablation is the recommended treatment of this condition.
