That sounds like an oversimplification, and probably a scare tactic. Hypertrophic cardiomyopathy, which is what happens when your myocardium is overworked, will cause conductance abnormalities which could lead to a pacemaker. Anabolic steroids also cause hypertrophic cardiomyopathy. This takes a long time, and clearly I was on that road until I stopped the meth.
