Method CTB by injecting a large dosage of calcium?

[aliasblue.]

So, I had read that an overdose of calcium can cause arrhythmia, which could result in an heart attack. So it could be possible to induce a heart attack by injecting yourself with a large amount of calcium. Do you guys think this method might work?

Itd work at a high enough dose. Might be extremely unpleasant though.

use potassium chloride instead, should be much faster and you only need 7g of it for IV.
