Rapid reversal of global left ventricular dysfunction after accidental injection of 0.75 mg epinephrine in a 20-year-old patient.

We report an accidental injection of epinephrine before spinal anaesthesia in a 20-year-old patient who subsequently developed immediate myocardial ischemia and global left ventricular dysfunction (ejection fraction of 20%). Hemodynamic status dramatically improved after nitroglycerin, calcium antagonists, acetyl salicylic acid and unfractionated heparin injections. Over 24 h, patient's ejection fraction fully recovered without kinetic abnormality.
