Good question. My wife has this along with four other heart issues. She had recently asked me if she could trip, but I’ve been avoiding the subject. I’d be willing to bet it’s OK if a person make sure their mental state is OK. Then again, a little anxiety and panic, and who knows.
I do have a friend that had a massive heart attack 10 years ago, and he still trips a lot. Of course, he had some stents put in and that probably made his blood flow better than ever. But that’s a different issue than PVC.
