Giant J (Osborn) wave due to bonsai abuse: Comments on clinical practice

Abstract

Background: Osborn wave, typically associated with hypothermia, is currently referred to as one of the J wave syndromes due to its clinical potential to develop lethal cardiac arrhythmia; it may rarely be observed in a non-hypothermic setting such as cannabis abuse. Case Report: In this paper, we presented two young cases who presented to the emergency services with unconsciousness, drowsiness, and hypoxia, and also J wave on electrocardiography (ECG) due to Bonsai abuse. Conclusion: Osborn wave may be a significant criterion to initiate close monitoring in a coronary care unit, with supportive treatment and mechanical ventilation as necessary in those patients who abuse Bonsai.
