Female 31, constant PVCs. What can I personally do to help myself?

The doctors in my country generally aren’t very explorative. They just want you to take a beta blocker and move on, no desire to help find a cause for PVCs that have bothered me greatly for 4 years. I’ve had a bad week of them, due to see a cardiologist soon. In the meantime, I need some advice on how I can help myself. I took magnesium glycinate and somehow, the PVCs got worse. I’ve improved my eating habits to prevent bloating or IBS. I take electrolytes. But for some reason these things have not helped me this week. I generally don’t have any other symptoms, besides discomfort and irritation. Sometimes a mild chest pain. In any case, this stuff is scary.
