Most common arrhythmia after reperfusion syndrome is: (A) AIVR, (B) VT, (C) Ventricular fibrillation, (D) PSVT
Answer is A. AIVR is currently defined as an enhanced ectopic ventricular rhythm with at least 3 consecutive ventricular beats, which is faster than normal intrinsic ventricular escape rhythm (<=40 bpm), but slower than ventricular tachycardia (at least 100-120 bpm) Ref Harrison 20th edition pg 1432
