Type II bidirectional ventricular tachycardia in a patient with myocardial infarction

J Electrocardiol. Nov-Dec 2009;42(6):631-2. doi: 10.1016/j.jelectrocard.2009.06.011. Epub 2009 Aug 13.


A 84-year-old man presented to the emergency department complaining of chest pain and palpitations. He had no history of coronary artery disease. The 12-lead electrocardiography showed bidirectional ventricular tachycardia (BVT). Coronary angiography revealed severe mid left anterior descending and mid left circumflex lesions. The BVT, in this case, was most likely due to myocardial ischema. The ethiology of published BVT cases are most commonly digitalis toxicity and rarely herbal aconitine poisoning, hypokalemic periodic paralysis, cathecolaminergic VT, myocarditis, and Anderson-Tawil syndrome. The patient had neither of these underlying conditions. To the best of our knowledge and research in the literature, there was no report of bidirectional VT in the patients with myocardial infarction.
