I was born with a 1 in a million heart birth defect that I didn’t know about until 2021 and I’m 78yo now. I wish I knew that an Electrophysiologist Cardiologist is a specialist that deals with heart rhythm issues. Regular Cardiologist simply prescribe Metoprolol for heart rhythm problems instead of referring you to an Electro Cardiologist. I ran into this issue with 3 different regular cardiologist and finally decided to be my own health activist. I did weeks of research before I stumbled onto an explanation of an Electro Cardiologist. That’s who every person on this forum should have for ANY heart rhythm problems NOT a regular cardiologist. This is just my opinion and not a diagnosis of your heart problem.
