Bradycardia (low resting HR)

My resting HR drops to 35-40 sometimes (66 years young) and I have some of the minor symptoms of Bradycardia. I have seen my primary care doc and had an EKG. The EKG was reviewed by a Cardiologist and based upon my history and physical condition it was determined this was something to watch but not be alarmed about. I have been searching for training plans/changes that reduce the risk of my Bradycardia symptoms worsening and havenít found anything. I have no problems with raising and lowering my heart rate during exercise/cycling and donít have any Afib symptoms.

Are there any exercise science based recommendations for training with Bradycardia?

I think the issue is the more exercise, the lower the resting HR. You might bump into say a weight lifting forum. Build muscle mass without necessarily building endurance.

I know there is a connection between bradycardia and anorexia + excessive exercise.

I don't know how dangerous it is in itself, although there have been reports of cyclists with bradycardia + blood doping, where their HR is already depressed, plus more oxygen carrying capacity in the blood further depressing the HR, plus "thicker blood", all combining to be a lethal combination.

I found this article on the LiveStrong site:

https://www.livestrong.com/article/4...f-bradycardia/

So, bradycardia in the elderly may well be improved by aerobic exercise.

I suppose it depends on the cause. Age? Hyper-fitness?

Thanks I had found that article in one of my searches. I doubt increasing my workouts and intensity is going to help me, I wish that was all it would take.

Make sure that, whether your preference is Fox or MSNBC, that TV stays tuned to the other one.

None of the medical professionals I've asked have any solid suggestions on avoiding or treating brachycardia. So my own way of treating it is to tell them, I've got a low resting heart rate. When they ask me, is it below 45 (or some other number)? I always answer "No." IOW, lie like a dog.

I think the only useful thing you can do is to get a Road ID that says "Normal resting HR is 35" or some such. It's just the result of genetics and a lot of riding. I can't imagine why one would worry about it. Not uncommon.

This is not something where you should be looking for advice from an internet forum. The term "bradycardia" means nothing more than a heart rate below the accepted "normal" range of 60-100 bpm. Many people through genetics and/or training have resting heart rates that are not "normal". One of my early mentors in the ER told me "Slow is good until it causes problems". You mention that you have minor symptoms of bradycardia. Only a qualified physician can tell you if those symptoms are anything to worry about or if your training is likely to make those symptoms worse.

At almost 65yo prior to my bilateral Orchiectomy for Prostate Cancer 4 years ago this month I had the mandatory pre-OP EKG and the reading was 32bpm. Nurse questioned it and I mentioned about just missing my 2015 IM70.3FL race due to the TRUS biopsy and my training for it and other events resulted in the lowered HR. I am often questioned about the low resting rate at first time doctor visits and prior to surgeries and simply reply "endurance athlete effect." While in ER following my 4/16/2011 bicycle crash at mile 72.5 of a 100 miler that resulted in a minor broken neck the HR monitor kept on going off also due to low HR. They re-adjusted and things were fine. My multiple ECHO results have shown a large athletic heart with some minor leaky valves but nothing really wrong.

Sort of what I have come to believe. It seems strange though that there appears to be zero info on the interweb about managing it for endurance athletes. My symptoms are mainly feeling light headed when I stand up after sitting/relaxing for 5 or so minutes. The more my fitness improves the more frequent the incidents of this. It seems that when you reach the point of slow causing problems you are a candidate for a pace maker. I could try a major reduction in training along with eating lots of junk food so I gain weight and lose aerobic fitness. This should increase my resting heart rate.

Hmmm... so, healthy, fit, and low HR.

As far as dizziness, you might look at orthostatic hypotension.

What is your blood pressure?

Make sure you discuss overall fitness with your doc before doing any invasive surgery.

Get standard blood panels to rule out other issues.

The dizziness has nothing to do with slow HR. Google postural hypotension. If the dizziness persists longer than 3 minutes, you have an issue. Otherwise, not. Don't complain about being in such good condition.
