Abstract

Background: Carbon monoxide (CO) poisoning is a public health concern with cardiovascular consequences like arrhythmias. Atrial fibrillation (AF) has been sporadically linked to CO exposure.

Case report: A 72-year-old woman presented with gait imbalance, dizziness, and headache. ECG showed new-onset AF, while echocardiography and brain imaging were unremarkable. Her husband exhibited similar symptoms, raising suspicion of CO poisoning. Carboxyhemoglobin was 2.9%. She spontaneously reverted to sinus rhythm with normobaric oxygen therapy. Systematic Review: 7 cases of CO-induced AF (ages 21-82) were reviewed. Most patients were male 4 (57%) and did not have a history of cardiovascular diseases 6 (86%). The most common symptoms were headache and nausea, each occurring in 4 (57%) cases. Rapid ventricular response was observed in 6 (86%) cases, with most reverting to sinus rhythm.

Conclusion: CO poisoning increases dysrhythmia risk through hypoxia-induced myocardial changes and voltage-gated channel alterations. Greater awareness is needed regarding its cardiovascular implications.

一氧化碳诱发心房颤动：通过病例报告和系统回顾报告病例揭示心血管频谱。

背景：一氧化碳（CO）中毒是引起心律失常等心血管后果的公共卫生问题。心房颤动（AF）与一氧化碳暴露偶有关联。病例报告：一名72岁女性，表现为步态不平衡、头晕和头痛。心电图显示为新发房颤，超声心动图及脑显像无明显变化。她的丈夫表现出类似的症状，引起了一氧化碳中毒的怀疑。碳氧血红蛋白为2.9%。通过常压氧治疗，她自然恢复了窦性心律。系统回顾：回顾了7例co诱导的房颤（21-82岁）。大多数患者为男性4(57%)，无心血管病史6（86%）。最常见的症状是头痛和恶心，分别出现在4例（57%）病例中。6例（86%）患者观察到快速心室反应，大多数恢复到窦性心律。结论：一氧化碳中毒通过缺氧引起的心肌改变和电压门控通道改变增加心律失常风险。需要提高对其心血管影响的认识。
