I had a follow-up appointment with my doctor this week regarding the weird sensation in my chest. Neither my blood work nor my stress echo test showed anything abnormal (other than an abnormal EKG), so in hopes of figuring out what I am feeling my doc ordered me a cardiac event monitor.
I must say, I am perversely excited by it. My particular monitor is called the LifeStar ACT. Basically, it's a contraption about the size of a stopwatch that I wear around my neck, attached to my body by three electrodes. It records and transmits my EKG all the time, and when I have an "event" (aka when I feel that weird chest sensation), I push some buttons and it sends the data to a Sprint cell phone (a way fancier one than is pictured on the ACT website, I might add) that I have to keep within 10 feet of my body. I feel very science fiction-y.
I thought I would only have to wear it for the weekend, but apparently I get to keep it for 30 days. Hopefully I won't actually have to wear it for that long--I imagine the newness will wear off fairly quickly (I have to sleep with the thing on) and I will want to be rid of it. But for now, it's a pretty cool new toy.
