Magnesium levels in acute cardiotoxicity due to aluminium phosphide poisoning

Significant hypomagnesemia and hypomagnocytia were observed in patients of aluminium phosphide (AIP) poisoning having evidence of acute cardiotoxicity while magnesium levels were normal in patients of AIP poisoning without shock or cardiotoxicity as well as in controls. There was a direct relationship between electrocardiographic findings and low magnesium levels. The mortality was also related directly to hypomagnesemia. The dose of pesticide also influenced the mortality adversely. Autopsied heart showed changes of toxic myocarditis on histopathology.
