  1. In this table are reported clinical events after the CRT-d implant in quadripolar vs bipolar group
  2. AF atrial fibrillation, CRT-d cardiac resynchronization therapy with a defibrillator, HF heart failure, ICD internal cardioverter defibrillator, VT ventricular tachycardia
  3. The symbol * was marking a statistical significant value, as p value <0.05
