A review of erythromycin-induced malignant tachyarrhythmia--torsade de pointes. A case report.

The term torsade de pointes refers to a ventricular tachycardia characterized by QRS complexes of changing amplitude that appears to twist around the isoelectric line and occurs at rates of 200-250/minute.
