I have a cousin on my dad's side who was diagnosed with IST at the same time I was. My sister, my dad, and my cousin's mom (dad's sister) have all been to the doctor about arrhythmias and episodes of tachycardia, but none of them have symptoms that are particularly disruptive. I thought this was unusual, as at the time of diagnosis, I was told by my electrophysiologist that IST was fairly rare.

My average resting HR is 97. In the mornings right when I wake up, it hovers around 140 for an hour or two. With even a tiny bit of exertion (walking more quickly than usual, riding my bike, bending over to pick something up) it easily reaches 195. The only thing that I've found that helps is laying down until it slows. When it gets that bad I will guzzle a litre of water and as many cans of V8 juice as I can handle, but that's not always helpful.

This is something I've been experiencing a lot lately. Some weeks it's almost a constant, crushing pain on the left side under my collar bone. Some weeks it doesn't happen at all, but it's definitely worrisome. My cardiologist suggested that maybe it was all in my head because I had been reading too much on the internet. I wasn't very pleased about it. My electrophysiologist was more understanding but still didn't seem as worried about it as I was. It's very bothersome and it makes me feel very anxious. I wish I knew what was causing it.
