Abstract:
A 67-year-old man was transferred to hospital because of acute circulatory failure resulting from sustained left ventricular tachycardia (LVT) and dysfunction. Transthoracic echocardiography revealed severely impaired left ventricular contraction and dyskinesis of the apical wall. Neither anti-arrhythmic agents nor direct current cardioversion was effective; the patient was resuscitated by immediate use of percutaneous cardiopulmonary support and intraaortic balloon counterpulsation. Ventricular contraction returned to normal following restoration of normal sinus rhythm with amiodarone and cibenzoline. The pathogenesis of LVT accompanied by transient ventricular dyskinesis is discussed with regard to the efficient use of a mechanical circulatory support system in resuscitation.
