This information may help you but being where you are, it may be hard to accomplish. I was born with a 1 in a million heart defect and my regular cardiologists didn’t even realize that fact. I had to do my own research before I stumbled onto what was wrong with me. I’m prone to going into Pulseless Ventricular Tachycardia, (fast beat), Bradycardia (slow beat), A-fib, spontaneous Blackouts (no warning symptoms) & spontaneous unconsciousness (no warning symptoms). I have encountered all these issues but received no help from any of my regular cardiologists, they thought I was making it all up. So I searched all the top hospitals in the United States (Mayo Clinic being the #1 hospital), and actually stumbled onto the answer. I needed to be seen by an Electrophisiologist, a heart rhythm cardiologist. What got me angry was the fact NONE of my regular cardiologists ever suggested I should see one after hearing my symptoms. So I would suggest you locate an Electo cardiologist if you are experiencing “any” kind of rhythm issues. I have the top Electo doctor in the same hospital my other cardiologist are in and my hospital is in the top 50 in the United States. I don’t want to list all the heart problems I have but you get the basic answer. Oh yeah, I’ve also had 3 heart attacks, the first one was when I was in the cardiology recovery room after a stent placement.
