Hi there! I have it too. I hate to say this, but for me it started 4 years ago and the jury is still out on the cause . I have an amazing cardiologist and neurologist. I’ve also seen an endocrinologist and my rheumatologist has weighed in . I was initially misdiagnosed with epilepsy and they thought I was having seizures . I did have a series of mini strokes and that’s been the closest thing ti an answer. I’ve also had a heart monitor implanted. For a while the thought was that I had a fib or heart block . The whole thing frankly has sucked and I had to quit my job in the film business which I had union standing and 25 years experience. It evaporated. That’s been an adjustment and a lot of soul searching . Well, there’s my long answer . I definitely suggest seeing a neurologist after you see your primary care doctor to rule out vasovagal, which I’m sure you’ve already done ….
