Abstract

A 75-year-old woman presented with medically intractable wide QRS tachycardia. She had experienced chest discomfort during a vertebral procedure and was transferred to our hospital. Electrocardiography showed sustained wide QRS tachycardia, which persisted in various QRS axes despite the repeated administration of electrical shock. Through amiodarone infusion and repeated shock delivery, the cardiac rhythm was stabilized to a sinus rhythm. Thereafter, the sustained ventricular tachycardia, for which electrical shock was necessary, occurred repeatedly for 12 hours, but then decreased in frequency and disappeared in 3 days. Echocardiography revealed akinesia of the entire left ventricular apical segment, and coronary angiography showed minimal coronary disease, which was compatible with a diagnosis of stress-induced cardiomyopathy. The patient recovered with general supportive care. Follow-up echocardiography revealed normalized left ventricular wall motion and systolic function.
