I think she needs to try another monitor before anything else. If she's getting interference it may be missing some beats, not her missing some beats. I assume this isn't one where she can download to a puter and look at a chart?
If someone has a Garmin Edge with a HRM she can borrow for a ride it would be worthwhile. She can upload to motion-based and compare her HR with her effort.
A few thoughts:
If there's a suspicion that it might be the HRM, then get on a spin cycle where you don't have to worry about crashing and see if the pulse, by feel, is correlating with the HRM. If not, your question may be answered.
Can she get her HR up to normal levels in another sport, such as running? If so, then I would think more about increasing fitness levels than a pathology, since her heart is capable of reaching a high rate.
Are there any symptoms associated with the (possibly) low heart rate while biking? They don't have to be chest pain or shortness of breath. If she's feeling like her legs are going numb, or lightheaded, then that needs to be checked out.
The Reader's Digest version of my story: I always had a low resting heart rate, in the upper 30's to low 40's. My actual max was correspondingly below my calulated max. A few years ago my resting heart rate started dropping into the low 30's and occasionally the upper 20's. My max went down to the mid 120's. I started having lightheadedness and a choking sensation with exercise. This progressed to the same symptoms with any exertion, like walking up stairs. I went to a cardiologist when I could no longer walk up stairs without getting short of breath. It took a while to diagnose, but my heart's pacemaking cells had quit. I am now the proud owner of an electronic pacemaker. I am also back to exercising as much as I want and even do triathlons.
Bottom line: If you can't easily see that it's the monitor or increased fitness then GET IT CHECKED OUT.
Hey,
I got up this morning ,and put the bike in high gear in the front (3 rings) ,and rode 21 miles. I gave it all I had ,and even had to stand up on all hills. I wasn't tired,but did pant going up some of the hills standing.
My avg was 115. My Max is usually 162 or something..that's consistent. I'm not fast...in fact I'm the slowest person I know. My avg over 20 miles-70 miles is always in the 13s. I feel great ,and I cant imagine what's wrong. The monitor is only about 5 months old. I'm not very good at using it ,and I did screw around with it a bit turning off the beeping sound....maybe there is something wrong with the monitor. My brother is a doctor...maybe Ill give him a call. Thanks for all the advise...Ill keep an eye on it.
Oh, my resting HR is about 48 ,and Im 53 yesrs old
Maybe borrow someone else's HRM? Maybe even wear both at once, and see if they correspond? And maybe get to the doctor before October. I'd say (well, depending on what the doctor says), really hammer one ride (you said you weren't particularly tired on your 21-miler, and that you consider yourself slow). 162 doesn't sound like an exceptionally high max, so maybe you haven't found your true max, and are really really well trained at slower speeds.
Just a couple of thoughts - good luck!
I understand the concern.
Have you done a manual count of your heart rate to verify the monitor.
I understand the concern and am intrigued by this...particularly, since if my heart rate was that low in exercise, I would assume it was improved fitness...so, I'll be interested in knowing the outcome.
I agree with prior posts, it may be time to see a doctor since presumeably, these symptoms would be easily replicated in a stress test.
Please keep us informed.
My average? Honestly I do not know as I have been too lazy to work out how to find that info on my HRmonitor :pQuote:

In a training ride with hills my heart rate will be between 97bpm and 160bpm.
On moderate hills I climb at a steady training pace with a heart rate now of no more than about 120bpm... 2-3 months ago the same hills would have me shoot up over 138/145bpm. Although this change wasn't literally overnight, it did happen over a couple of weeks.
(When I started cycling about 3 years ago even moderate climbs would have my HR into the high 150s, 1602 ans even 170s.)
I am finding I am noticing changes in my heart responses seem to happen in stages... with plateaus... but this may be because I do not keep an every-ride-check on my average.
Sorry... not much use to you in terms of how you/Suzie use your monitors...
OK... when I do this my HR goes up to high low 160s... in a race situation that would be high 160s and early 170s.Quote:

This does ring alarm bells - especially when Darcy posts that it seemed to work as expected when you went for a run... Check that out, and how it fits you (is your bra/crop top interferring with the position?).Quote:

One other quick thought: Is someone you regularly ride with wearing an HRM that interferes with yours?
Sounds like it may be the transmitter or receiver going out...or perhaps you are getting the transmitter and receiver too far apart somehow so it quits measuring some beats? Do you wear the receiver on your wrist or is it on your bike? Have you started standing more frequently which may put the two too far apart?
Have you recently picked up the volume or intensity of your rides recently? A couple of times this season I've been training too much (too long, too hard, too frequently). When this happens I find that I can't get my heart rate up to where I expect it to be even though I'm feeling ok otherwise. For me this situation signals muscle fatigue and a couple of days of complete rest have helped get me back on track.
Have you noticed an elevation in your resting heart rate as well? This is also a good measure of overtraining.
As the others have mentioned it is also a good idea get checked out by your doctor since this change happened relatively quickly.
Hope you get it figured out soon and that all is well.

So have you been to a doctor yet?
Thom's been worried about you since I first read your post. :)

Please go see a cardiologist and do a stress test with EKG. Some offices are now equipped with stationary bikes in addition to the tread mill.
Unless you are uber fit ultra-athlete, low 40's heart rate, doesn't sound quite right. Also have someone else wear your HRM who knows what their HR is and see if it agrees with them. And for you to try theirs out. Compare the result...
And are you drinking lot of herbal tea by any chance? Like hibiscus flower tea? or something else. If you are, check with herbal medicinal books and also tell the cardiologist before the stress test. I sort of remember that the hibiscus flower has an effect on your blood chemistry and heart rate.

i would tend to agree with roadraven. the average may be low, maybe you spend a lot of time recovering. do you watch your heart rate when you're exerting yourself? what does the hrm show as your max after the ride?
if you hit a healthy max i would say you're fine, but i would really worry if you just cannot lift your heart rate.
call your brother!!!!
