We report the case of a patient who developed a life‐threatening polymorphous ventricular tachycardia (PVT) after six weeks of treatment with amiodarone. The Q‐T interval was markedly prolonged at 0.86 second. The drug induction of PVT was strongly suggested by the fact that PVT resolved four days after withdrawal of amiodarone when the Q‐T interval had shortened to 0.60 second; the arrhythmia has not recurred in the nine months of follow‐up since then. Amiodarone, though a very effective antiarrhythmic agent, may induce serious PVT.
