Catheter ablation for Atrial fibrillation: Electrogram-guided methods [Ablación cardiaca auricular: estrategias guiadas por el mapeo de electrogramas]

Radiofrequency catheter ablation has evolved into an effective treatment option for drug-resistant patients with atrial fibrillation. Electrical isolation of the pulmonary veins has become the standard ablation strategy mainly in patients with paroxysmal atrial fibrillation. However, the success rat...
