[Complete heart block and myocardial ischaemia during a severe anaphylactic reaction].

An 83-year-old man had to be operated under general anaesthesia for a head skin tumor. The preanaesthetic exam of the cardiovascular function was reassuring but a cardiac arrest with a complete heart block occurred a few minutes after induction of anaesthesia. Resuscitation managing was successful but a myocardial ischaemia appeared. Biological tests confirmed severe anaphylactic reaction. The electrocardiographic expression, pathophysiology and management of cardiac anaphylaxis are discussed.
