I have a diagnosis: ASH aka HCM. Generally my condition isn't life-threatening and the palpitations/irregular beats can be controlled with medication. Now that I know that, they are more annoying than terrifying.
Oh, and stimulants exacerbate the condition, so I'm on strict instructions to avoid caffeine, even in chocolate. (Oh my!)
I'll need to find a cardiologist in my new community.
Just another thing on my getting settled to-do list.
