Metabolic syndrome is associated with a poor outcome in patients affected by outflow tract premature ventricular contractions treated by catheter ablation

Variables are expressed as mean ± SD or median (IQR: 25th percentile, 75th percentile) if not normally distributed.
AADs, antiarrhythmic drugs; HR, heart rate in beats for minute (bpm); PVC, premature ventricular beats; QS wave in DI derivation on surface ecg; RF, radiofrequency catheter ablation.
