You're a "Flatliner".zacklaws said:Whilst out riding today, I remembered a strange series of spikes that happened last winter 2008/2009 on one ride I did.
On downloading from the Edge into TC, I noticed 7 strange spikes, but unlike a normal spike, upwards, these went down to zero for a slight pause before going back to a normal rate.
When I looked closely as to the exact spot on the first occurence on the map, I noticed that it happened after a long steady climb and my HR was high in the 180's and I was starting a slow decent, when my HR dropped to zero. It was then that I remembered that I always take a drink at that point, just after I get my breath back before racing off. When I looked at the other spots too, they all tallied up with places where I took a drink.
Why it happened? I have not the faintest. I have some presumptions, that maybe when taking a drink, I made a movement that broke contact between my HR monitor and my chest, maybe moving the water bottle across my chest broke the signal to the receiver. My other big theory why it may have happened was, it was a very cold bitter day, just above freezing, my drink was bitterly cold and perhaps it had chilled enough to be just above freezing, and then when I drunk it, the shock internally was enough to just shock my heart into pausing briefly, one of the symptoms of "cold shock" is cardiac arrest, maybe I was lucky. Or there again, the fluid going down my neck may have interfered with the monitor somehow messing up the electrical pulses from my heart.
Whatever caused it, its never happened again.

Perhaps it's because you ride in a built up area?
At a guess, their may only be one entry, but when you search through the file, just keep searching. Just type in a figure you presume you was probably doing that seems reasonable, import it back into TC and see if it looks right.gb155 said:Thanks everyone, I will have a mess around, I assume there should be just one figure of 77.9mph ?
Excellent, Many Thankszacklaws said:At a guess, their may only be one entry, but when you search through the file, just keep searching. Just type in a figure you presume you was probably doing that seems reasonable, import it back into TC and see if it looks right.
The files are quiet large, but don't be intimidated, look for what time it happened before you start editing in TC, then just look amongst the time stamps when you open the exported file and you will soon find it if you do it manually, otherwise just type 77.9 into "find"
