ischemia resulted in a progressive increase in pulse width and rise time and a decrease in rate of rise of voltage ( dv/dt ) of the local electrograms from ischemic zones reaching a maximum within 2.4+/-0.3 min ( mean+/-se ) at the time of onset of severe ventricular dysrhythmias , all of which returned toward control before the cessation of the dysrhythmia ( 33.5+/-1.5 min after coronary occlusion ) .
