I recently had an arterial bypass operation on my leg, to stop a blood clot from going to my heart. All went well, but the medical team mentioned that I have A fib, which I already knew.They also said they had found “A weird electrical quirk” in my heart, which I had been told about by my cardiologist years ago. He’d thought I had had a heart attack but after running tests he said I wasn’t in bad shape, just had this “Weird electrical quirk” which had made him think that. But actually it is normal (for me).So what the hell could it be and why would it be normal for me, but an indicator of medical issues on some one else? I have to wonder if I’m reptilian from Mars or a freak of some kind.
