An 11-year-old boy collapsed during morning assembly at his junior high school. The automated external defibrillator detected ventricular fibrillation and provided shock delivery. He was successfully resuscitated and reverted to sinus rhythm. Electrocardiography showed ST-T elevation in the precordial leads. Echocardiography and angiography demonstrated akinesia of the apex and mid-wall of the left ventricle with preserved contraction of the basal segments, which suggested Takotsubo cardiomyopathy. The patient and his family had often eaten uncooked crab, and his father had a past history of infection with Paragonimiasis westermani. The patient had had a persistent cough and chest pain for several weeks. Chest radiograph showed cystic cavities in the left upper lung. Microbiological examination of the sputum demonstrated an egg of P. westermani and immunological assay showed a raised antibody titre to P. westermani. On the12th day of admission, he developed seizures, and magnetic resonance imaging demonstrated cerebral involvement. After the administration of praziquantel for 3 days, the clinical manifestations improved immediately, and echocardiography normalised within 3 weeks. The patient was discharged on the 32nd day + and follow-up was normal. Takotsubo cardiomyopathy following a potentially fatal arrhythmia is a rare cardiac complication associated with pulmonary and central nervous system infection by P. westermani.
