Torsade de pointes. An unusual form of ventricular tachycardia

A 65-year-old man with hypertension and glaucoma developed diuretic-induced hypokalaemia complicated by torsade de pointes ventricular tachycardia. This arrhythmia requires accurate recognition so that appropriate therapy may be administered. When torsade de pointes is diagnosed, a careful search for underlying causes should be conducted as reversal of these may prove curative, as in this case.
