1967–1997: Thirty years of cardiac arrhythmias

Prevention of Ventricular Fibrillation During Acute Myocardial Ischemia: Control of Free Fatty Acids

“…With the hope of identifying the patient most vulnerable to primary VF, particular attention has been given to the electrophysiological changes that occur during acute ischemia (3)(4)(5). Dispersion of refractoriness (eg, prolongation of the QT interval and JT dispersion), irregularity of the R-R interval, and R-on-T ventricular ectopic beats have all been studied extensively in the hope of predicting the patient vulnerable to VF but none are either sufficiently sensitive or specific to be reliable.…”
