A 63-year-old female presented to a freestanding emergency room with dizziness, palpitations, and hypotension, The patient was found to have an irregular wide complex tachycardia, consistent with ventricular tachycardia, hypomagnesemia and severe hypocalcemia. The tachycardia was refractory to treatment with IV amiodarone and magnesium, and only resolved with correction of the serum calcium. Review of the medical record revealed an echocardiogram 19 years earlier reporting left ventricular dysfunction. The patient was unaware of this diagnosis and was not taking medical therapy. Echocardiogram revealed no significant change in left ventricular function, and coronary angiography showed no significant coronary artery disease. The patient's nonischemic cardiomyopathy may have been a predisposing factor for the arrhythmia presentation. We explore a hospital admission involving the rare association of hypocalcemia and monomorphic ventricular tachycardia, which is not well documented in the literature.
一名63岁女性因头晕、心悸和低血压前往独立急诊室就诊。患者被发现有不规则宽QRS波心动过速，符合室性心动过速、低镁血症和严重低钙血症。该心动过速对静脉注射胺碘酮和镁治疗无效，仅在血清钙纠正后才得以缓解。查阅病历发现19年前的超声心动图报告显示左心室功能障碍。患者不知道这一诊断，也未接受药物治疗。超声心动图显示左心室功能无明显变化，冠状动脉造影显示无明显冠状动脉疾病。患者的非缺血性心肌病可能是心律失常表现的一个易感因素。我们探讨了一次住院病例，该病例涉及低钙血症与单形性室性心动过速的罕见关联，这在文献中记录较少。
