Accelerated idioventricular rhythm

This rhythm strip is taken from a 67 year old man with chest pain who had ECG signs of inferior-posterior  wall M.I. upon the arrival of paramedics.  He had a recent (5 day) history of cardiac cath and stent placement.  During his treatment, his condition and ECG signs improved somewhat, and it was felt that he spontaneously reperfused during transport.  Often, during reperfusion of the heart after a total or near-total occlusion, dysrhythmias will appear.  They are usually transient.  This strip shows accelerated idioventricular rhythm.
