While his condition improved with standard therapy (including corticosteroids, diuretics, and supplemental oxygen), he developed symptomatic sinus bradycardia (heart rate nadir: 37\u202fbpm) 2\u202fdays after discontinuation of these medications. The bradycardia resolved with intravenous potassium supplementation and fluid resuscitation, and his heart rate recovered to 59\u202fbpm. This case highlights that a rebound in vagal tone and steroid withdrawal may contribute to severe bradycardia during the HAPE recovery phase, warranting heightened clinical vigilance.<\/jats:p>","DOI":"10.3389\/fmed.2026.1754071","type":"journal-article","created":{"date-parts":[[2026,1,30]],"date-time":"2026-01-30T06:42:29Z","timestamp":1769755349000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Symptomatic
