Sorry to say YES, but has the congenital heart diseases have been ruled out. I had a case of 11 years old boy (during last Christmas) who reported in ER shockingly he had severe over dose of heroin
and collapsed in an hour due to cardiac arrhythmia
. Now a days age is not accounted for Myocardial Infarction
Best we can do is educate our children against these street drugs.
