Introduction: Tachycardia-induced cardiomyopathy (TIC) was first described in 1913 in a young patient who presented with congestive heart failure (CHF) and atrial fibrillation (AF) with rapid ventricular response, which resolved by controlling the arrhythmia.
TIC is defined as systolic and/or diastolic ventricular dysfunction resulting from a prolonged elevated heart rate which is reversible upon control of the arrhythmia or the heart rate.
Atrioventricular reentrant tachycardia (AVRT) is most of the time paroxysmal and could rarely appear in incessant forms, being one of the most frequent causes of TIC. Once they become incessant, it is unlikely to stop it with pharmacological treatment, catheter ablati-on being the principal therapeutic option.
This case report intends to synthesize the atypical case of a patient without structural heart disease, trans-ferred to our ward after an incessant wide QRS supra-ventricular tachycardia episode, which lasted four days, with hemodynamic instability and drug-resistant, that stopped only by emergency intracardiac overdrive sti-mulation and subsequent catheter ablation.
