―症例―くも膜下出血後の心電図異常Torsade de pointes

An Electrocardiographic Abnormality Called Torsade de Pointes in A Patient of Subarachnoid Hemorrhage

I．はじめに

　くも膜下出血後の心電図異常の報告は多い^4,9），なかでもtorsade de pointesと呼ばれる心室性不整脈は危険な不整脈である^1,5）が，まだあまり多くの報告はなされていないようである．われわれも最近，この不整脈を脳動脈瘤手術中にきたした症例を経験したので，若干の文献的考察を加えて報告する．

　We report the findings in a patient in whom torsadede pointes atypical ventricular tachycardia occurred as a complication of subarachnoid hemorrhage.

　The patient was a 54-year-old female and she was admitted to our hospital to treat gastric ulcer on Octo-ber 8, 1985. The electrocardiogram on admission showed mild left ventricular hypertrophy. She complained of severe headache and nausea in hospital on November 10 and she was transfered to our department. Her consciousness was clear. Computed tomography revealed a subarachnoid hemorrhage and left carotid angiogram showed a left middle cerebral artery aneurysm.
