training heart rate

[Kaillb]

in the last weeks, sometimes when I am training (running intervals), during my jog between intervals, my pulse meter starts to show a very high pulse. My max pulse is about 170, but during these periods it may register over 200 for 1-2 minutes.I have written this off as a problem with my pulse meter.This has happened about 4-5 times in the last month. Can it be that my heart is actually beating this fast or must it be a technical problem with my watch. Normally my pulse goes up to the 150s during an interval and goes down to 100 in the 2 minutes jog between the intervals. I am a 69 year old male.

Sometimes my pulse meter will give a false reading while exercising.
I think it may be the moisture or sweat that affects the pickup on my chest.
If it is too loose, it may also do that.  I use the type with the chest strap transmitter.  I also use a small amount of lubricant on the pickups.  You need good contact to get good readings.

Can you FEEL it? (before, during and after)
Is it linear?  (HR accelerates and recovers in proportion to physical output)

I doubt SVT would be something that you discover at age 69... doing intervals.

I'd go with the old runner's adage: listen to your body.  Then combine that with the soundman's adage: use your ears, over the meters.

If you're worried, go to your doc and have him order a Holter monitor and runn the heck out of some intervals.
