Cause of death
Methylamphetamine intoxication leading to agitated delirium and extreme exertion-induced cardiac arrhythmia
AI-generated summary
A 33-year-old female with a history of methylamphetamine use consumed the drug and became acutely intoxicated, exhibiting agitated delirium and bizarre behaviour searching for her son. She was violently assaulted by residents while attempting to enter homes. Upon police arrival, she was found collapsed and covered in blood with head, arm and skeletal injuries. Police correctly recognised a medical emergency, restrained her gently to prevent further harm, and placed her in recovery position to prevent positional asphyxia. Despite immediate ambulance request and CPR, she died from methylamphetamine and exertion-induced cardiac arrhythmia. The coroner found police response appropriate and professional. Clinically, this case highlights that excited delirium from stimulants carries profound cardiac risk, particularly with extreme exertion, and that rapid escalation of care and CPR are crucial.
