irregular heart rate question(13 posts)

irregular heart rate questionScottH
Jun 13, 2001 6:58 AM
I had a very strange thing happen to my heart rate last night when I stopped suddenly at the top of a small hill about 5 minutes into our Tues night ride. My HR dropped from 130 something down below 80 and then back up to over 130 within a matter of seconds. I could feel it happening, thud, thud, thud, etc, and I looked down at my HR monitor and confirmed it.

Anyone ever have this happen? I get this occasionally when I'm just loafing around at home but never with such a swing, usually only 10-20 beats. I have yet to ask my doctor about it.

Checked with my wife who is a nurse in the cardiology department. She would adivse you to see your doctor and explain your symptoms. Could be nothing or any number of things. Impossible to diagnose in this setting. Good luck.

I'm a physician (noncardiologist). I think it is a very good idea to get this checked out. Your doctor will probably get an EKG, but it might not show anything if you are not having the arrhythmia at the time of the test. They can send you home with a device called a Holter monitor which will electronically record a basic cardiac strip for 24 hours. I think you could even go biking with it or do whatever seems to bring your irregular heart rate on. Then you bring it back to your doctor to have it analyzed.

I had the opposite problem when I first started using a HRM. My pulse rate zoomed from 135 to 290. Freaked me out. Turned out I was riding next to some big-ass power transmission lines that skewed the reading.
Ask your doc about arrhythmiaBrian C.

I had that once, but it wasn't bike related. It was very strong palpitations that would come out of nowhere, last a few seconds then go away. After a battery of tests, we never did get to the bottom of it. After a few weeks it went away. I figure it was an adverse reaction to St. John's Wort.
You don't want to mess around with your heart.

Stay off the caffeine, especially strong coffee like espresso. This can cause problems for some peole. If you must drink coffee try not to drink more than 2-3 per day. But definitely see a doctor first. CHEERS.

I'm glad to hear I'm not the only one. When my palpatations begin, its a sign that I need to lay off the mo-jo. I'll be doing the halster test myself on Friday. For whatever reason, the increased aerobic/anaerobic activity has agrivated my arithmia. I'm getting all checked out just to be safe. I was told I can ride while wearing it--just not to go over board. My Doc also told me the palpatations could be related to animia. Though animia affects women more than men, it makes sense that it might increase with cycling--since aerobic activity utilizes iron.

Good Luck! If you do the halster thing, you get to wear a nifty fanny pack all day--oh joy!!

i used to be very concerned about them but now im used to them..caffinee and stress make it worse..generally they say if the heart goes back to normal you are fine,but, might as well get it checked out anyway...your chances of it being dangerous are slim unless it makes you dizzy, and even then they can give you drugs and the like..dont let it stress you out, it does for alot of people, i was one but now im used to it, some people get them much worse.
were you drinking water when it happened?cyclopathic

my HR can drop from 150 down to 110 /hey I am still riding!/ when I take a good seep. Natural reaction to reduced O2 intake.

can't disagree go and get checked might be something else going on.

They ran an EKG and found something strange so I had to go in this morning for blood work and a chest X-ray. I was told the iregularity could just mean I have a strong heart or it could mean something like an enlarged ventricle?? Anyway, I won't find out until next week.
Good Luck.....Len J

The good news is that you found it before any serious problems. Let us know how you make out.

I have the left ventricular hypertrophy that he may be talking about. Basically a slightly thicker heart wall muscle. It can thicken from not be active or from heavy exercise. I usually get the palps late at night when I'm overtired...I only notice them because my resting heart rate is now in the high 40's- low 50's. Get a stress test done with a cardiologist and set your mind at did mine!
