Size of early myocardial ischemia on ventricular fibrillation threshold in rabbits / 中国病理生理杂志

ABSTRACT

The effect of early changing stage ischemic size on ventricular fibrillation thresh old(VFT), blood pressure and plasma noradrenaline concentration was observed in 30 rabbits with constant heart rate and excition of vagus in some animals. The result suggests that VFT can be influenced by changing myocardial ischemic size; but the influence has no relation to heart rate, blood pressure, plasma noradrenaline and vagus. The result points out that the size of early stage myocardial ischemia has relation to the occurrence of ventricular fibrillation.
