Scary Couple of Weeks!

It will be 2 weeks ago tomorrow that I was doing a tough 5 hill repeat workout on Grovedale Hill that I noticed I was not feeling the best. Lori, Robert Jr. and Dennis followed me up the hill for the first 3 and I managed 1 more....got 4 of the 5 and had to stop...definately something wrong! Got home and downloaded the Garmin....HR maxed at 218!! So my first assumption was there was something wrong with the HRM for sure! Checked that out and it was A-OK.....so my next guess was that i have a cold or virus and I will be better soon. So the next day was a 2 hr endurance run that felt like 5 hours!....HR hovering around 180....yikes!! Decided then I needed some time off to kick this "bug". After much procrastinaton and "suggestions" from everyone around me, I went to Emergency a week ago last night and before I could say anything else, I was lying on my back with oxygen up my nose and wires attached everywhere on my body!...to be continued
