control ( non-shocked ) heart responses to adrenaline were highly reproducible in terms of inotropic , chronotropic and coronary vascular behaviour.3 results from the study document myocardial dysfunction within 4-6 h following an ld ( 70 ) endotoxin administration on the basis of increased left ventricular end diastolic pressure ( lvedp ) , decreased cardiac power and myocardial efficiency , and depressed negative and positive dp/dt parameters.4 findings suggest significantly altered responsiveness of the myocardium to infused adrenaline at rates of 1 , 2 , and 5 mug/min with concentrations between 10 and 1 ng/ml blood .
