CAORSI, Walter Reyes; VARELA, Gonzalo; TORTAJADA, Gustavo  e  CORTELLEZZI, Zuly. Arrhythmia-induced cardiomyopathy. Rev.Urug.Cardiol. [online]. 2019, vol.34, n.1, pp.307-341. ISSN 0797-0048.  https://doi.org/10.29277/cardio.34.1.21.

Cardiac arrhythmias are a frequent and usually not considered etiology of ventricular dysfunction. They could be the single cause or a contributing factor of ventricular function compromise. Catheter ablation is an available resource that brings us the possibility to definitively cure several arrhythmias, confirming the diagnosis of arrhythmia induced cardiomyopathy improving or normalizing ventricular function, and in addition to modify the prognostic. We will mainly discuss atrial fibrillation, the arrhythmia more often associated in practice with heart failure. Also, we will analyze the role of premature ventricular contractions as cause or contributing factor to ventricular dysfunction, usually a controversial topic.
