Yeah, I'm not entirely sure about all the rationales behind the device. I just agreed to do the clinical trial, then wore the thing about a day and ditched it. :-)
My doctors initially suggested that I might need a implantable defibrillator if my EF didn't recover sufficiently, but it turns out that by about 3 weeks after, my EF was back close to normal, so no defibrillator required. Now I'm hoping I can talk my cardiologist into taking me off of Metoprolol at some point, since I do some competitive endurance athletics and that stuff supposedly hurts your performance. And from what I've been reading, some newer research suggests that there's no real benefit to continuing to take it more than a year after an MI.
