in conclusion : 1 ) sudden prolongation in refractory periods following reperfusion leads to an overshoot resulting in a dispersion of refractoriness temporally related to the onset of ventricular arrhythmias and 2 ) re-entry , and not enhanced automaticity , appears to be the mechanism for postperfusion arrhythmias .
