Meth induced tachycardia and palpitations

How long can this persist after use?

Not an addict, or a regular user, but once in a while (maybe once or twice a year) I will sporadically use.

It’s the day after I got high (I’m no longer high) and I cannot sleep due to the tachycardia and palpitations. I can just feel my heart racing and pounding in every position I lie in. Also, get paranoid that it’s going to give out at any moment.

I feel fine except for this. Could it be permanent? Am I likely to have cardiac arrest?
