During a recent intense work out with my trainer I began feeling weak after approx 50 mins. I had to sit down and after about five minutes of my HR being at 100-90, I went pale, felt light headed and sweat intensified. My trainer took me into the restroom and began splashing cold water on my head. My heart rate then dropped to 60 (I was wearing a monitor) and began dropping by 10 beats every 10 seconds until I told my trainer I was going down. He helped me to the floor at which point my HR was at 32. Within 5 seconds of being on the floor, my HR recovered to 80 and I was able to sit up. With ice on my neck and head, my HR stabilized at 90. After a hot cold shower and a protein shake, I was able to drive home 15 to 20 minutes later with an HR of 75 to 85. Two hours later, my doctor performed a physical exam and BP was 120/80 and HR 70, EKG normal and all signs of stroke were tested and non present.
He sent me to emerge where all blood tests and a second EKG showed negative. I am 40 years old, very active, work out 2 to 3 times per week, play hockey and baseball regularly. For two days prior to the incident, I had a flare up of my IBS and lost quite a lot of fluid however I did try to drink more water to compensate. I have also had bouts of panic disorder/ depression in the past and I am the CEO of a media company. I am currently wearing a holter monitor, 24 hours and have an echo cardiogram scheduled in a few weeks. The terms presyncopal and vasovagal have been thrown around by nurses but no real information has been given to me as yet as to what may have happened. Can you shed any light on this?
