How I can find my night time heart rate?

[Mick50]

Hi all 

Iam wondering how I can find my nite time heart rate. Is it possible to split the daytime and nighttime heart rates. I only seem to have a graph for resting average heart rate. So for example if I wanted to know my lowest heat rate while sleeping is this possible thanks mick

@Mick50You can create a Custom Activity. When you use it on the PC you will need your calories, when used via my Android it gives you the calories.

If you use this technique on active periods it will average the calories and you could lose Active Minutes.

The images here are an 11 hour period last night.spikes are bathroom breaks. I have also "homed" in on a 10 minute period. When doing this you only get a plot every 10 seconds. A few months ago it was every 2.5 seconds.

Thanks for reply but as you can probably guess iam new to this lol I went activities and it is set on steps and I don't know what to do or change it. If you imagine you are taking to a child it will be easier for me to understand 😂😂

@Mick50We will help you get this information..

On your PC you only need to be at your Fitbit Dashboard and then click Log, Activities..

Then follow this link which will guide you through creating a Custom Activity.

When you are examining your sleeping HR I would use the calories you see on the Activity Log barchart for the sleeping period.  Hover over one of those bars which is 5 minutes of sleep and multiply it by the minutes of sleep you are analysing divided by 5 to gives you calories for the sleeping period.

ie 6 calories/5 minutes..

    8 hours sleep = 480 minutes divided by 5 gives you 96 x 5 minute time periods

Therefore calories = 96 * 6 = 576 calories. This will not affect your active minutes.

Get back to us...and we will help you through this...

Sorry didn't see the link thanks mick

[Colinm39]

@Mick50 You click on the blue "follow this link". Give that a go.

[Colinm39]

@Mick50 You can get a quick check of your HR by tapping your RHR on your phone Dashboard. Tap the resulting graph and you can check the readings.

Cheers for that 😎 iam getting the hang of things now lol

[Colinm39]

@Mick50 Great, it takes some time when you receive your device and try to search on the Forum for answers. Keep asking because most of us went through the same issues.

I have just activated my Charge 2; I am using the unit to track my heart rate as I have been diagnosed with Bradycardia (slow heart beat).  I have followed your steps in setting up my dashboard to track the heart rate, but I don't see the detailed graphs that you show in your posting.  My graphs are more generalized; obviously I am missing something.  Also, I will need more days of tracking to get more meaning full graphs.

Thanks,

ceholli

@ceholli can you post a screen shot, then we would know what your seeing.and will be able to help

[Colinm39]

@ceholli To create the detailed graphs I use a Custom Activity and if you follow the link in my earlier post April 8th... it explains what to do. If you choose the full 24 hours it will average your calories over 24 hours and you will probably lose Active Minutes. After I print the graph I delete the record.

The graphs didn't help me because I have a genetically low HR and I found that Fitbit varied on the pulse data being used.. In this link from last year you can see what the issue is..

The 3 larger spikes are my bathroom breaks..and the other restlessness was me going to bed after moving many things for our painter renovator. Too close to bed time.. I still had nearly 8 hours sleep (by Fitbit) because I went to bed before 11pm

Today for 2 minute periods I received 11 plot points for around 2am and 21 plot points for for 1-45pm.  The lowest while sleeping last night was 45bpm.

Fitbit haven't answered whether they average or only record a beat when it changes..

Maybe @LanuzaFitbit who has replied in the link I have included can help us...

[Colinm39]

@ceholliI have just downloaded my data from an external source and it averages 6.3 plot points/minute for 17 hours today.. Typically 3-7 plot points while sleeping and 7-11 while awake.

The same thing a few days ago when I achieved 45 minutes of Active minutes, high calorie burn etc.  The same, 9050 plot points for 1440 minutes..Ave 6.3 again..  My RHR was 52 on the day of the data below.. So it peaked at over twice my RHR.. My maxHR is 143 for my age.

In any comment I make, I accept that the Fitbit hasn't the accuracy of a medical device and there are many Fitbitters who have taken appropriate action when they felt the results made them feel uneasy. A trip to their GP and in turn experts helped them through the issue.

When I examine the data it appears that must be some rationalizing because in the table below the plot points from external are exactly the same as my Fitbit Custom graph.  From these you can see its useless for my missing heart beats. Cardiologist passed me on all counts.

So all we need is for Fitbit to explain how the pulses are stored/rationalized.

Attached is a screenshot from this morning; showing my sleep and then waking and walking my dog. The graph shows my heart rate, but I would like more detail in the graph if possible. I really need to know what my lowest heart rate is during the night and at what time(s).

Thanks for your support!

@ceholliThe Custom graph allows you to see the HR but you have to judge the time, or, when you have established where the lowest HR is you create a smaller time period Custom Activity and home in on the area for a more accurate time estimate.

The screen shots show the coarser phone RHR view and the PC Dashboard Custom graph.  to establish the low HR period.

Hey @Colinm39, @ceholli and @Rich_Laue!

As @Colinm39 mentioned, Fitbits are not medical devices and the very best options for any conditions should be discussed with your physician. 

As for how the Blaze tracks your HR, it will continuously track your HR whenever the green LED on the back is turned on. Keep in mind that if you have set the HR setting to Auto and are not moving for some time the LED will stop recording continuously and will just turn on for a small moment in order to sample your HR. 

I hope this brings some clarity and answers to the situation. Let me know if you have any further questions.

[Colinm39]

@LanuzaFitbitThanks for the reply. Early this morning I set my Blaze HR to "ON" between 2-20-3-30am. The downloaded data is presented the same way. Averages about 6 pulse plot points/minutes.. Every 10 seconds. I would have thought having the HR setting set to permanently on would have achieved a better result.

Even if the Blaze does a continuous plot as you say there is obviously some filtering going on when the data is stored. All we need Fitbit tell us that that occurs and the pulse plots we see are the result of actuals, even if averaged and don't average out the highs and lows.

As I mentioned in earlier posts I used to get a pulse plot typically every 2.5 seconds.

@ceholliThanks for the earlier reply but the screen shot didn't show.  If you are having difficulty with that this post shows how to achieve that.

If you could describe "the more detail", would also help us.

Colin: This is another screenshot; you can see the heart rate for my sleep time is in the low 40's, but I can't get actual numbers, only approximate.  I guess for my needs this will probably work as I am looking for trends, but would like more detail if possible.  My Dr. had me wear a heart monitor last week and will likely repeat the test again next week after I have a stress test.  Until a few months ago my resting heart rate was around 60 now it has dropped into the low 40's.  He is trying to determine why my heart has suddenly slowed down and is hinting that I may need a pacemaker.  The use of the Fitbit is for my own awareness and tracking, I will leave the real tracking to the Dr.  It is comforting for me to be able to monitor my heart rate as the Dr. emphasized  very strongly to me that if my heart rate dropped again and stayed in the low 40's that I was to call 911 immediately.  Ceholli, California

@ceholli Thanks for the screenshot. You can only get the detail from the RHR tile on a phone or create the Custom Activity on the PC Dashboard. Do you need help with that?

My b-in-law is 77 and has had a Pacemaker for over 20 years. Just had it upgraded. His symptoms were similar to yours, sudden low HR, but with dizziness etc.
