the results showed that : ( 1 ) vft is a quantitative index of myocardial vulnerability : ( 2 ) met , positively correlated with vft , might become a substitute for vft as an index of vulnerability to ventricular fibrillation : ( 3 ) atenolol , both in normal and ischemic myocardium , is able to make a significant elevation of vft , which is considered as an antifibrillation effect : ( 4 ) nitrendipine exerted no apparent effects on all the parameters .
