There are three mechanisms of arrhythmia: automatic, re-entry, and triggered. The most common triggered arrhythmia is Torsades de Pointes. It is a benign arrhythmia which requires no specific treatment. Possible mechanisms of ventricular arrhythmias elicited by ischemia followed by reperfusion. Do not treat AIVR.

On the basis of unresolved angina, cardiology decided to perform rescue PCI. The following ECG was obtained.
