Many years ago I dated an ER physician who got one of the Tylenol/cyanide poisoning cases in the early 80s in the Chicago area. She said she tried to draw blood from a vein for analysis but it came back bright red, so she assumed she had hit an artery instead. Only after repeated tries did she realize that it was indeed the vein.
 


Yes, it is possible, because cyanide blocks one of the crucial enzymes involved in oxidative phosphorylation, which means the energy levels in cells are decreased immediately and soon after there is no enough energy left for vital functions such us breathing and pumping blood. Depending on the dosage, death can occur in a matter of minutes (maybe even in less than a minute).
