The prognostic value of J‐wave pattern for recurrence of ventricular tachycardia after catheter ablation in patients with myocardial infarction

Background J‐waves and fragmented QRS (fQRS) on surface ECGs have been associated with the occurrence of ventricular tachyarrhythmias. Whether these non‐invasive parameters can also predict ventricular tachycardia (VT) recurrence after radiofrequency catheter ablation (RFCA) is unknown. Of interest, patients with a wide QRS‐complex have been excluded from clinical studies on J‐waves, although a J‐wave like pattern has been described for wide...
