Ventricular arrhythmias associated with lidoflazine: side-effects observed in a randomized trial.

Twenty-four patients received either propranolol, lidoflazine (Clinium), or propranolol/lidoflazine combinations in a study designed to evaluate the effect of these drugs in angina pectoris. Five patients developed ventricular tachycardia when receiving either lidoflazine or lidoflazine and propranolol in combination; one of these patients died. In addition, one patient died suddenly while being treated with propranolol alone. Lidoflazine therapy was associated with a significant prolongation of the QT interval of the electrocardiogram. Lidoflazine either alone or in combination with propranolol, appears to induce ventricular tachycardia.
