der gerauif said:I am 53 years old male and my heart rate easily goes over 170 when I do a
run of more than 1 hour. I run regularly since a quarter of a century, and I
don't think there has been much change in my HR (not sure, though). On the
other hand things must be changing when you get older. The official
recommendations usually include rules of thumb that indicate that at my age
my HR should stay below 155 or so, implying that I just shouldn't run
anymore, just jog. My HR is regular and when I really try I can get it to
190. When would you guys start worrying?

I've been lurking, thinking I might get help here on pretty much the
same question. I did post my question on a group where I am a regular:
rec.bicycles.misc. If you do a google groups search on high maximum
heart rate you will find this topic comes up on many different groups
and there are quite a lot of people out there with maximum heart rates
unusually high for their age.
I was diagnosed with type 2 diabetes a year ago and was determined to
control it with diet and excercise. I gradually increased my exercise
beyond the walking (with hills) I've done for years. By last May I
tried running, but a hip problem came up, so I took up bicycling for the
first time since college. The bicycling works wonderfully for me--I did
a 62 mile organized ride in early October. I'm still trying to build up
the running very slowly, hoping to be able to do a sprint triathlon next
May in honor of my 50th birthday.
I bought a heart rate monitor a month or so ago, thinking that it would
encourage me and help me keep up my effort on the bike. I went and rode
up the steepest longest hill I have successfully ridden. I was
mind-boggled that my heart rate hit 195. I was puffing harder and
harder but I could keep riding. I did a little research and satisfied
myself that it is normal variation. See particularly
http://www.athletictrainingservices.com/MHR.htm
But I told my doctor about it the next time I saw her, and she said that
I should have it checked out, as heart disease can have no symptoms,
particularly in women. She sent me to a cardiologist with a diagnosis
of tachycardia (though my resting heart rate is 60). The cardiologist
said I should have a stress test and an echocardiogram. I did the
stress test this past Thursday (if you do it make sure that your doctor
writes on the order to let your heart rate go high--otherwise they stop
you when you reach the maximum for your age). I felt great--at a heart
rate of 191 I was by no means out of breath and was eager to keep going.
But the doctor monitoring the test insisted that I stop because an
abnormality had showed up in the EKG when my heart rate went above 170.
The abnormality was that the ST part of the wave dropped down below
the isoelectrical level, which can be a sign of a partial blockage.
Other people have that abnormality when nothing at all is wrong. The
cardiologist wants me to have a heart catheterization to check for a
partial blockage, and I incline to go ahead and do it (some friends are
saying get a second opinion and maybe a less invasive test, but I think
I need maximum information if I want to continue high intensity
exercise). I've always had very good cholesterol numbers and have no
family history of heart disease so I find it hard to believe I could
have a blockage, but I want to know for sure.
I asked the cardiologist whether if the catheterization shows no
problems he would still be concerned about my high maximum heart rate.
He said he would be, and would want to give me medication to lower it.
I think he is wrong in that, and I will find a cardiologist who
specializes in athletes (anyone know one in Atlanta?) before considering
medication. In the meantime, I very much would like to find medical
articles that discuss normal variation in maximum heart rate to show the
cardiologist. Telling him that I have seen a lot of people on the
internet who have high maximum heart rates isn't going to get me very
far. I've done some searching on pubmed without any luck so far--if
anyone knows any such articles I would very much like references.
I'm still in the middle of my story--the catheterization is scheduled in
a week and a half. What I can tell you so far, is that doctors, at
least the ones I've seen, do see it as something that ought to be
checked out, even in the absence of any chest pain or other symptoms.
I've come down in an awkward middle place--I think the high maximum
heart rate can be a normal variation and the doctors are wrong to see it
as a problem by itself, but I also want to keep getting checked out
until the doctors are satisfied that there isn't something else wrong.
