Sudden rapid heart rate while exercising

While doing my regular morning exercise on the treadmill today I had
something strange happen. I keep my heart rate between 95-105 bpm
normally, after about 20 minutes I felt this vibration (like a shiver}
go through my body from my feet up to my head, this lasted maybe 2-3
seconds, immediately my heart rate almost instantly went up to 135bpm.
I then slowed down but could not get my heart rate below 100, so I
stopped exercising and rested but my heart was still way to high. It
stayed at around 90 while resting and shot up almost instantly to 120
when walking at a slow pace. My resting heart rate is about 60bpm.I
did not have any chest pains, heavy breathing, nausea, shortness of
breath, sweaty or clammy fealing. I called my GP and he advised me to
go to Emergency, when I got there my resting heart rate was 98bpm. By
the time they got around doing an ECG it was 58bpm and there were no
abnormalities in the ECG (this was done 2 1/2 hrs after the initial
incident) so I was released with no explanation. The rest of the day
my heart rate was fine and I felt OK other than a bit of anxiety
because of the "unknown". I am a male 48yrs, had double CABG done in
2000, I take aspirin, atenalol, and Lipitor daily. Have any of you
experienced a similar situation or have any ideas what happened?

Would suggest you see your cardiologist. It is like s/he would
recommend a stress test.

Humbly,

Andrew
