  1. Data are expressed in frequency (percentage)
  2. 1The percentage was calculated as the number of each type of ablation as denominator and the number of success as numerator
  3. 2It included any focal atrial ablation not mentioned in this table (e.g. LA or RA free wall, interatrial septum, slow pathway, or bypass tract)
  4. AF, atrial fibrillation; AT, atrial tachycardia; CFAE, complex fractionated atrial electrogram; DC, direct current; FIRM, focal impulse and rotor modulated; GP, ganglionated plexus; IAS, interatrial septum; LA, left atrium; PVI, pulmonary vein isolation; RA, right atrium; SVC, superior vena cava
