High pulse (110) before getting out of bed

2 weeks post CRT D and I've noticed on my fitbit that my pulse is over 100 before I get out of bed. My first check up is in 2 weeks but I'm just wondering if this is common after a new pacemaker and if its cause for concern. I did phone the hospital but they said they couldn't say anything until I came in 2 weeks. To be honest, without the fitbit I wouldn't be any the wiser and when I went to bed my BP was 119/72 so it seems to be some sort of dawn phenomenon similar to blood sugar. During the day the pulse seems to stabilize.

count manually

Don't go by the fitbit, count manually. If your rate truly is staying over 100, call the doctor again. 

I developed tachycardia at rest following my pacemaker implant

Yes, I agree, my blood pressure and heart rate which are always low naturally, rise around 5 am for a couple of hours so this could be partially due to the dawn phenomenon.  It may be that a change in when you take any blood pressure medication (taking at night rather than during the day), might help treat any heart rate increases at rest, in the early morning?

After my pacemaker I definitely had an increase in my heart rate at rest and was quite worried too.  Unlike you, however, my heart rate was much higher at rest 150+ bpm and I did feel very symptomatic.   A heart rate of around 110 bpm would not unduly concern my doctors (but of course I do not have your heart condition or an ICD) since this would only be slightly tachycardic.  The fact that you do not feel poorly with this heart rate is a very good sign too that your heart is not labouring, but I am glad that you have spoken to your doctors.  If they are concerned, they will treat it.  Your blood pressure of 119/72 is really excellent and the fact that your pulse stabilises during the day is good news too.  Are your arrhythmias under control.  I believe you have been treated for Atrial Flutter, but perhaps you still have an underlying atrial tachy arrhythmia present which might be causing your symptoms?  Hopefully this will settle as you heal.

As long as you don’t start getting symptomatic, I would say just be a good observer and make a note of your Fitbit pulse in the early morning and take this evidence with you to your two week check and compare with whatever they report.  I too would check pulse manually (I check neck pulse) to feel if it is regular fast, or irregular fast.  I sometimes use a good blood pressure monitor which does a great job with both blood pressure/heart rate, especially when the rhythm is "regular".  I have tested at my GP's surgery and it has been found to be accurate.

Hope you make good progress

Gemita - I've not had arrythmias since my Ablation nearly a year ago and I don't take BP meds; it's usually normal without them. I use a BP monitor to test my BP , the fitbit is only to check on myself throughout the day in case the arrythmias come back; as I write this it shows 80bpm which is a little high for me but not concerning. I'm probably over analysing but interesting you had similar experience after your pacemaker although I don't take BP meds so I have less to blame. I assumed after the op that my pulse would be lower, at least at rest.

Dawn Phenom

I exhibit a strong dawn phenomena that begins as soon as I start to wake up, and my insulin pump is programed to counter that.  It would be natural to show an increase in HR due to the regulatory hormones involved in getting the body up for the day.

I suggest that you don't go by one reading, but an average over 10-14 days.  Also, the fitbit can be inaccurate at times.  Using a chest strap and a BT app on your phone may be a good way to validate your readings.

When we are sleeping, everything slows down.  It makes sense to me that just as we awaken, things start up again, so there may be a brief time of increased heart beats.  I have always felt like that, before and after getting a pacemaker.  

I just accept it as how my body works and IMO you should stop looking at the Fitbit.

If you feel uncomfortable or ill, check your heart rate either manually or with a stethescope, not a Fitbit (or similar).

You are also new to all this, in recovery from your op so it could be hyper awareness on your part.  Perfectly normal, we all react differently to implanted devices.

If you feel fine, just ignore it and enjoy your days.

 

Best Wishes,

I wouldn't be alive if it wasn't for pacemakers. I've had mine for 35+ years. I was fainting all of the time and had flat-lined also. I feel very blessed to live in this time of technology.
