Abstract
- Diabetic neuropathy is one of the most common complications of diabetic mellitus and has myriad clinical presentations. Amitriptyline is an effective drug for painful diabetic neuropathy, but has a wide variety of cardiovascular effects. We report a case of amitriptyline-induced ventricular tachycardia in a patient with painful diabetic neuropathy. A 48-year-old man with no history of heart disease was treated with amitriptyline for the past 2 months. The dosage of this drug was gradually increased and the maximal dose was 170 mg per day. Prior to administration of this drug, his chest X-ray and electrocardiogram were normal. On admission he complained of chest discomfort and palpitation for 3 days, but his vital sign was stable. The electrocardiogram showed a wide QRS complex with a rate of 170 beats per minute. The ventricular tachycardia was successfully treated with electrical cardioversion.
