Abstract
Lidocaine is one of the most frequently-used drugs to suppress ventricular arrhythmias; however, it has arrhythmogenic action when given in excess or along with other antiarrhythmic agents.
A case of ventricular tachycardia (torsades de pointes) after a conventional dose of lidocaine with successful resuscitation following discontinuation of the drug is reported. Although such complications are rare, one would anticipate an enhanced effect of lidocaine to a patient with prolonged Q-Tc interval due to bradycardia, congestive heart failure or ischemic heart disease.
