Analysis of the electroencephalogram in growing calves by use of power spectrum and cross correlation

Electromechanical dissociation (EMD) occurred in a 20-year-old woman 48 hours after an overdose of atenolol, despite intensive treatment of the beta-blocker poisoning (gastric lavage, charcoal, glucagon, epinephrine, atropine, correction of electrolyte abnormalities, administration of fluids, cardiac pacing, and mechanical ventilation). Administration of calcium chloride during EMD repeatedly restored blood pressure. Therefore it may have a role to play in management of atenolol overdose.
