"Torsade de pointes" in a patient with variant angina.

Ventricular tachyarrhythmias have been well documented in patients with variant angina. Episodes of torsade de pointes have been described infrequently. We report a case of a 60-year-old male with a previous history of one vessel artery disease and a successful coronary angioplasty with stenting of the left anterior descending artery, who experienced an episode of angina at rest and electrocardiographic evidence of self-terminating torsade de pointes. After a negative coronary angiography and a positive hyperventilation test, the diagnosis of variant angina was considered and beta-blockers discontinued and calcium channel antagonists prescribed. No other episodes of angina were documented during the following 6 months of follow-up.
