Cause of death

Unascertained; likely fatal cardiac arrhythmia secondary to electrolyte disturbance and QT interval prolongation

AI-generated summary

Robert William Keith, aged 34, was found deceased in his caravan on 28 June 2010. He had a long-standing history of paranoid schizophrenia managed with risperidone injections and oral medications under a Community Treatment Order. Post-mortem examination revealed elevated urea and creatinine consistent with dehydration and/or renal impairment. He had a documented prolonged QT interval on previous ECGs and multiple prior hospital admissions for vomiting-induced electrolyte disturbances (hypokalaemia, hypochloraemia, metabolic alkalosis). The coroner concluded his death was likely due to an acute electrolyte disturbance causing QT prolongation and fatal cardiac arrhythmia. Clinicians should recognise that antipsychotic medications and recurrent electrolyte abnormalities increase arrhythmia risk, necessitating regular ECG monitoring, electrolyte surveillance, and aggressive management of vomiting episodes in vulnerable patients.

Contributing factors

  • chronic electrolyte disturbances (recurrent hypokalaemia, hypochloraemia, metabolic alkalosis)

from

he identity of the deceased was Robert William Keith

occurred on or about 28 June 2010

la Unascertained

in the following circumstances:

Mr Robert Keith was aged 34 years when on 28 June 2010,

" he was located in the area of the caravan where he lived

alone. Ambulance officers attended but were not able to assist Mr Keith. Police investigated the scene and found no evidence of foul play.

Mr Keith was last seen on the previous evening at about 10.00pm.

Mr Keith had a medical history which included treatment for paranoid schizophrenia. At the time of his death Mr Keith was subject to a Community Treatment Order, and was prescribed medication in the form of fortnightly Respiradone Consta injections and oral medication. Mr Keith had regular reviews of his condition and had been subjected to Community Treatment Orders for some years, Mr Keith was last seen by his.case manager on 7 June 2010.

On that occasion, no paranoid ideation was present and he reported sleeping and eating well.

In April 2010, Mr Keith was admitted to hospital for management of metabolic alkalosis, secondary to an episode of vomiting.

A full post mortem examination was conducted by Dr Melissa Baker, Forensic Pathologist, of the Victorian Institute of Forensic Medicine, who formulated the cause of

Mr Keith’s death as “unascertained”, She did not find any evidence of natural disease, which may have caused or contributed to his death, Dr Baker noted that post mortem biochemistry “revealed an elevated urea and creatinine consistent with dehydration and/or renal impairment”, She also noted that Mr Keith had previously been treated, with multiple hospital admissions, for “vomiting leading to hypokalaemia, hypochloraemia and metabolic alkalosis with associated renal impairment.” She stated “electrolyte disturbances such as hypokalaemia can lead to cardiac arrhythmias.”

In her report and in her evidence, Dr Baker stated it had been previously noted that Mr Keith had a long QT interval on his ECG at hospital, for which there can be many causes, including electrolyte disturbances such as Mr Keith had experienced on many occasions, Some anti-psychotic medications can also lead to the prolongation of the QT interval and predispose to fatal cardiac arrhythmias. Long QT interval can also be genetically based and Dr Baker recommended that there be family follow up. It is not nown what was the cause of Mr Keith’s long QT interval, but it was certainly consistent with his presentations in relation to renal impairment. .

Dr Baker found no evidence of any injury which may have caused or contributed to Mr Keith’s death.

Although it is not known what caused Mr Keith’s death, it is ikely that he was experiencing an episode of electrolyte disturbance, evidenced by the elevated creatinine and urea, which may have caused a prolongation of his QT interval, which in turn could have lead to a fatal cardiac arrhythmia,

There are no suspicious circumstances surrounding his death.
