I have a hard time believing you could get an accurate reading with your
pulse so high

Why should that be a problem?
I've never heard of it.
The doctor determined by bloodpresure while I was pedalling on a
hometrainer,
heart rate over 180.

<DISCLAIMER> I don't really care about this all that much, so this is my
opinion and I won't argue it if you disagree - fair enough?

Now on to your comments and why I said why I said.
I have no doubt that your doctor can take a blood pressure reading
accurately - that's why he went to med school - to learn about that stuff.
Do you have his training? I don't especially when taking my own blood
pressure under conditions of high level activities. I can watch the needle
on the guage move to determine the high/low numbers but keep in mind that
both the position, size, and quality of the equipment can radically effect
measurements. That's when using traditional cuff meters, when using
electronic devices the quality, position, and stability of the patient come
into play as well. A lower quality device with a low sampling frequency
will not get accurate readings of pulse when the pulse is high. I'm sure
your doctor has better equipment, but I personally can't afford medical
quality gear. So I use my equipment as suggested and as only an estimate.



More that likely your pressure meter is having a hard time distinguishing
between systolic and diastolic pressures - assuming you're using an
electronic BP gauge.

Why should it have a problem with that?
I've used my meter many times while working out on my home trainer and
never got the impression that the meter had problems distinguising between
those values.

Would you even know if you were getting bad readings? Consider that for a
bit beyond the obvious "what do you mean, I know how to take a blood
pressure reading!" retort. I'm dead serious, would you know if the
equipment was off by 10%? 15% 20% 50%??? I think you'd notice a 50% error,
but again the sampling frequency of the equipment (if digital) plus the
technique of using the equipment can dramatically impact the results. Are
you using a proper size cuff? Do you have the guage in the right spot?
We're you moving your arm a bit during the testing? Remember you're taking
this at 180 bpm (as you stated above), presumably you're tired, sweaty, your
coordination is off due to fatigue - all of which can impact the accuracy.

That's all I'm saying. I'm not calling the poster a moron. I'm not
claiming I'm right and you're wrong. I'm just questioning the validity of
results given when taken under duress and suggesting that maybe the poster
shouldn't worry about it.
