Had my date with the (quite handsome) cardiologist this morning. He ordered me an ekg, which took all of two minutes and came back abnormal (like the last one I had) but he says that it’s fine. (If you’re interested in that sort of thing, I have flipped Ts, which is also what your ekg shows if you’ve had a heart attack. I didn’t, though; I just have a wonky heart.) The persistent lightheadedness is probably because my blood pressure is low. I have orthostatic hypotension, but I get lightheaded just sitting around thinking or whatever.
He also told me that the weird veins in my arm are maybe just how it is from now on; or maybe I need a little more salt or water (or both) in my diet. He says it’s not related to me feeling like I’m going to faint. It’s remotely possible (but he really thinks not, and I think not even moreso) that there’s an obstruction (a blood clot) somewhere, or there’s an even smaller chance that it’s something worse, which he defined only as "exotic," because why worry over nothing? Basically, we talked for almost an hour (!) and he showed me his support hose.
It was a pretty good date.
I’m going back next month so he can watch me run on the treadmill (his idea and phrasing) and do an echocardiogram before and after exercise. He gave me his phone number and email, but I’m totally not going to call. Instead I’m taking Jenny’s advice and playing hard to get.
