However, there are limited reports on the increased risk of bradyarrhythmia for arrhythmia-free SAS patients with SAH. Case Description: A 31-year-old woman with SAS developed low-grade SAH and underwent coil embolization on postbleed day 1. Following a coiling procedure, she experienced worsening episodes of sinus arrest lasting up to 12 s and required a temporary pacemaker. Frequent episodes of sinus arrest were detected for the next 4 days. Thereafter, all types of arrhythmias gradually decreased, and she eventually recovered to be arrhythmia free. Conclusion: Acceleration of sympathetic nervous activity caused by acute SAH may predispose patients to bradyarrhythmia with SAS and elicit asystole. The coexistence of SAS and SAH should be recognized as a cause of life-threatening sinus arrest, even if the severity of SAH is low grade.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/88f35696-1b1e-4067-ab0f-79e9f6132c39/featured/hero-1781563383269.png","publishDate":"2020-06-20T00:00:00.000Z","doi":"10.25259/SNI_66_2020","categories":["Neurovascular","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2020/06/10092/SNI-11-156.pdf"}
