Though the basis for administration of digitalis appears sound, little is known regarding dosage toxicity relationships during shock.7 In the present study the tolerance of the heart to acetyl strophanthidin was determined in the normal state and during endotoxin shock.

Methods  Mongrel dogs (10 to 20 kg) were anesthetized with intravenous pentobarbital (30 mg/kg) and ventilation maintained with a mechanical respirator using room air. Lead II of the electrocardiogram was continuously monitored and periodic segments recorded. An intravenous catheter was placed in a peripheral vein and acetyl
