Yeah, apparently. I mean, mfer's 53, at that age you tend to pick up shit. Luckily he has enough money to take care of it. They're still doing shows and that: https://www.psychopathicrecords.com/

Violent J announced that he’s suffering from the more serious form of Atrial Fibrillation (otherwise known as a-fib), which causes the heart’s upper and lower chambers to beat irregularly and out of sync with each other.

I've heard it said that he has congestive heart failure. I don't have the source on that though. People were speculating that's why he missed some concerts recently, but it turned out to be cellulitis.
