Need full case study with results discussion Introduction etc. Dont use guideline answer ok need full accurate case study.    Case History A 32 year old male was found unconscious in his flat following a night out with  friends. Attempts to resuscitate the male were unsuccessful. The postmortem  indicated sudden cardiac death through cardiac dysrhythmia (arrythmia). There was  no medical history of previous heart disease. Two opened packets of Jumping Beans were found on a table close to the body. A  specimen of cardiac blood was taken and submitted to the toxicology laboratory for  analysis along with the two Jumping Beans packets.  . Guidance for Preparing the Case Report The coursework assessment for the module is to prepare a case report in the form of  a case report scientific paper published in the Journal of Analytical Toxicology. This  guidance information has been taken from the Instructions for Authors for the  Journal of Analytical Toxicology however please use the…
