67M concerned about my HRV. It fluctuates between 20-25, occasionally dips into the teens. My cardiologist told me not to worry about it and questioned the accuracy of the measurement(Versa 2). Everything I read says that HRV is the trending heart health measurement and mine is very poor. My cardiologist is at the Cleveland Clinic so I assume he knows what he's talking about. I had a mild heart attack in 2017. My resting heart rate is low 60's.
31M previously very active prior to all this (sub 6 minute mile, often do 30 mile hikes, work out almost every day)
I don't have much data prior to this but my HRV is horrendous for my age since long hauling. Typically 19-24. I've had others use my Fitbit and they have normal rates for our age (60s-70s) so I don't think there's any issues with the device.
Curious those of you that wear a Fitbit or another device that tracks HRV have you seen significant changes in your HRV?
My main symptom is never ending chest pain and some numbness throughout the body that comes and goes.
Is there anything I should do about this?
As a scientist, I lobe that TR has an amazing data set from riders and hope they continue to consider ways to contribute to the field from it. My experiences training raises two questions for me on heart rate that I would love to get feedback on:
As I work through my own sets of VO2 max repeats with rests, my recovery to a kind of baseline HR takes longer based on A) recovery rate from previous workouts and B) number of intervals completed in this workout. What is this rate of HR recovery called (it is a specific kind of HRV), how is it measured, and how reliable is it as a measure of fitness and recovery between workouts. As ramp tests possibly become less necessary throughout training (replaced with adaptive training), could there be a VO2 Max workout that could be used to measure this HRV rate of return of decreasing HR between intervals? This feels really useful for thinking about “number of matches”, Event FTP calculation and the need for rest days.
Edit: Based on responses, I clearly wasn’t clear in the above post. Here’s an example of what I mean:
After warm-up, say you settle into a coupled heart rate of 120. Then you do a series of 120% FTP intervals. In each interval, your HR reaches slightly higher HR, say a peak of 168. Between intervals and after the series, you HR drops back towards the baseline of 120. If it never returns to 120, there is drift or decoupling, but in addition to that metric is the rate of return, the deceleration of HR. This slope starts steep but the rate lessens after intervals (it takes longer for the HR to return to baseline). What is this rate of decelerating HR called and couldn’t there be a specific test in TR to measure it? Would it provide a useful metric for more variable events that require surges and recovery?
And secondly, more generally, is TR partnered with any outside research group to publish out of their extensive data sets?
Hi guys, I just wanted to share my experience with minoxidil for anyone checking this forum. I tried topical liquid minoxidil, alcohol based. 1mL in the morning and evening.
I tried it for a week and today I decided to stop. Actually immediately after day one, I noticed just some weird feeling. I guess it were heart palpitations. It was very minor and I was 2nd guessing myself if it could be because of the minox. i thought maybe I'm just imagining things as I read about the possible side effects and ofcourse that lingers in your mind when you start. One evening I went to bed and felt my heart pounding and couldn't sleep as I was too focused on it. Today I had to help a friend move. It was the only time this week I did any physical activity and I noticed my heartrate was really high for even small things as lifting some boxes. I track it with a Garmin watch. The watch also measures stress, calculated with my heart rate variability. It has been trending up for precisely a week, equalling the stress levels I had when I was ill 2 weeks ago (flu or covid). These levels of stress are very unusual and basically only seen if you're ill or if you do a very intense sport activity.
I wonder how common this is. Anyone had a similar experience? is there a solution?
cheers!
Hi everyone
I've experimented with a few different breathwork practices during the year.
I'd like to know a bit more about the link between resonance/coherent breathing and improved heart rate variability (HRV), which seems to be one of the most touted benefits of this technique.
I read in a study that it is only possible to improve your HRV with this breathing technique if you are able to measure your own HRV in order to determine the most appropriate breathing pattern specifically for you (e.g. 5:5, 6:6 etc. rather than just assuming one).
So my question is, if you are unable to measure your HRV and determine the most appropriate pattern for yourself, is this technique still worthwhile?
I'm sure it is, would just love to hear some opinions!

Hello, I have a Vivosmart 4 and was wondering if anyone has had any luck accessing their raw heart rate variability data with it? (Rather than the metrics that use HRV as an input, like stress.) I don't think Garmin will give it to you directly, but it looks like their might be third-party apps? Thanks!
EDIT: We decided to use the new Fossil gen 6 for raw ppg extraction and it seems to be going well right now. We have not attempted to derive HRV yet.
Hello everyone,
I am an undergraduate student working on a research project which hopes to utilize raw sensor data from a wearable device. I will be working on developing a smartwatch app to extract and store various sensor data for analysis.
Right now, I am looking into different platforms and watches which would be best suited for this sort of task. In particular, I am in need of a device which can provide accurate and relatively continuous PPG (heart rate) information. I am especially interested in any device which allows for measurement of heart-rate variability (i.e. I hope to obtain inter-beat interval data frequently and continuously). I realize this can be a tough metric for many smartwatches, so an accurate-enough PPG which allows for IBI calculation would likely be sufficient.
I would appreciate any insight any of you could provide about the capabilities of current Wear OS in general in this regard, and if there are any particular devices you would recommend for accurate health sensing.
I appreciate it!
Has anyone noticed very drastic changes in their heart rate variability? I range anywhere from 10ms to 171ms throughout the day and it spikes up/down very often. I also suffer from pots like or dysautonomia symptoms for the past 5ish months (post covid). Let me know if anyone has any similarities to this!
It's a fascinating measurement for body stress and I'm trying to find how the body recovers after surgery.
I decided to check my yearly average HRV with the health app on my iPhone since I wear an Apple Watch. My average is 32ms, which apparently is really low (not good). What’s yours?
I'm using EliteHRV and having good results with resonant frequency breath training as described here:
Lehrer, P. M., Vaschillo, E., & Vaschillo, B. (2000). Resonant frequency biofeedback training to increase cardiac variability: Rationale and manual for training. Applied psychophysiology and biofeedback, 25(3), 177-191.
That paper established 20 minute training sessions as the norm, which seems to have been what's used in pretty much every study since.
Is there any info out there on what happens with more time per session, or more frequent?

Hello,
Is there a way to have my Apple Watch 6 measure my HRV regularly? I see a data point for it in the Health App pretty randomly, something consecutive hours, sometimes nothing for 12 hours. Doesn't seem to be correlated with using the Breath App either.
I need some articles written about HRV for a blog. Looking for 1 page articles of 500-700 or so words. Open to as many topics as you feel you can confidently write about. Would need article linking and scientific references where necessary. It's an extremely niche knowledge set - I would rather someone knowlegeable rather than someone with writing credentials. Not just looking for a bargain, I would rather set up a really good ongoing partnership.
Open to discussions about what this might entail - happy to use an escrow service. Please pm me with your experience and any questions you might have!
Thank you
Is this metric worth taking any action on? I’m young (27) and my watch has reported an average HRV of 35ms over the last year. That’s pretty low for my age from what I’ve gathered.
I’ve never used a dedicated heart rate monitor before, just the sensor on my Apple Watch and Fitbit, but I want to graduate to something more accurate. Do any of the polar products measure heart rate variability in a meaningful way? I generally want to use the sensor to see my heart rate during tennis and monitor it after for help with my recovery (potentially sleep sometimes)
Anybody know what data they offer?
I have been playing with Welltory since yesterday after seen people using it here. Very interesting app which showed that something weird is going on. My sympathetic nervous system is way up, even if I am having a restful day, among other things. The fluctuation of the indicators fit my own feelings pretty well too. Could be an interesting tool to bring some hidden data into the surface and help.
I am thinking of buying a fitness tracker that can record hrv in real time (like the relatively cheap Garmin vivosmart 4).
Have you found a way to increase HRV and increase parasympathetic? I tried cold shower this morning (I mean somewhat cooler, not all the way cold since I am just starting to experiment), and it had amazing effect on those indicators.
