Abstract：
A 60-year-old man was referred to our hospital presenting with unconsciousness due to severe hyponatremia. The twelve‑lead ECG on admission exhibited prominent J waves in the inferolateral leads. During the treatment for hyponatremia, ventricular fibrillation (VF) occurred and the electrogram (ECG) after the VF incident exhibited marked ST elevation in the inferolateral leads. An Ach provocation test induced vasospasms in the right and left coronary arteries and J wave augmentation, suggesting a high risk for vasospastic angina. Finally, a subcutaneous implantable cardioverter defibrillator was implanted in the patient. We hereby discuss the possible contribution of hyponatremia to VF episodes in early repolarization syndrome based on the present case.
摘要：
一名60岁的男子因严重低钠血症而失去知觉，被转诊到我们医院。入院时的十二导联心电图在下外侧导联中显示出明显的J波。在低钠血症治疗期间，发生了心室纤颤（VF），并且VF事件后的心电图（ECG）在下外侧导联中显示出明显的ST抬高。Ach激发试验引起左右冠状动脉血管痉挛和J波增强，提示血管痉挛型心绞痛的风险很高.最后,患者植入了皮下植入式心律转复除颤器.我们在此讨论低钠血症对早期复极综合征中VF发作的可能贡献。
