    Sudden Drop in Heart Rate & Dizziness while exercising.
    Yammy Yammy
    February 19, 2009

     While on a treadmill, I suddenly felt weak, tired, dizzy, cold sweaty, and my heart rate dropped from 130 to 89. After stopping and getting off the treadmill, the dizziness got stronger, my hearing went a little muffled and my heart rate dropped to 60. It felt like I was going to pass out (I've never passed out before). A minute or two and some deep breaths later, my heart rate returned to the high 90's and low 100's and the dizziness was gone. This never happen to me before and it has happened twice in two days now. I warmed up on a stationary bike just before the treadmill and my heart rate was at a steady 110/120 with no problems. I also was able to do a weight training session earlier in the morning with a steady heart rate of 125.

     

    Some suggested I "BONKED" but I have read about Vasovagal, Pre Syncope, Bradycardia, and Angina. Any ideas?

    Aloha Yammy,

     

    It has been a long time since you asked.  I just started participating here at MyHeartCentral.com so I am just now seeing your question.

     

    I am curious as to how old you are and if you have any medical history.  With so little information to go on, I'd guess that it might be a elecrical problem within your heart.  Perhaps you have something like a "short circuit" in your hearts electrical conductivity.  A cardiologist can monitor you with a holster when you exercise to see what your heart rhythum looks like.

     

    The other thought I had is low blood sugar.  If you have either of these problems it is important that you address them.

     

    Good luck and wellness!

    Carrie

    Know this is a long time ago you asked but I had the same symptoms and turns out I did actually pass out a couple of times, while not exercising.  After 2nd event in a few months they checked me in overnight and found out I had Sick Sinus Syndrome and my HR was cratering, to the point it would actually stop for several seconds at a time, most often when I was sleeping (so much fun waking up with a crash team in your room).  Anyway had a pacemaker put in and no problems since.  BTW, I was a 50 year old, active, otherwise healthy male who cycles (just did a total of about 100 miles this weekend, 60 flat on Sat and 35 climbing on Sunday), hikes, plays basketball and such. 

     

    So if you have something like this talk to your doc.  They might schedule for you to wear a halter monitor or schedule you for something called a tilt table test.  Both are definitely worth your while.
