[Sinus arrest: severe complication of intravenous lidocaine].

Sinus arrest occured after intravenous administration of Lidocaine in therapeutic disage in a patient with coronary artery disease and sinus node disease. This complication of Lidocaine, though rare (this case is the fourth of the literature), induces to use this drug carefully in patients with sinus node disease. Temporary pacing is recommended if Lidocaine must be used in this group of patients.
