Increased HR, any ideas please?

Hello there I hope you are all doing well,


I have been experiencing some strange symptoms for a couple of weeks now and i wondered if any of you have had similar experiences, or have any ideas as to what could be going on. 


My heart rate keeps randomly increasing from its usual 65 ish beats to around 95 beats. It stays like that until I eventually go too sleep, and this could be for hours. I'm not quite sure what is causing it? when it happens i can feel my heartbeat in my chest and i feel quite shaky and almost weak? with some dizziness and the need to sit down. 


Im not quite sure what can be causing this, but it is causing my quite a bit of anxiety and discomfort. I am also getting almost daily headaches, and extreme tiredness, which is made worse when this happens. 

If anyone has any ideas that would be great please,


Thank you,



higher hr

Can you send a report with your remote monitor? Take note of what time the episodes are happening and let them know. Sometimes the reports can give an idea what is happening.

Things that make my heart rate jump are alcohol and caffeine, even tiny amounts can get me sometimes while other times I can have a big coffee and nothing happens. 

No stimulants

Thank you for your messages and suggestions. I am finding this really strange as I have had no stimulants at all, no caffeine, alcohol or anything like that. 


Im really not sure what it is but it doesn't seem normal,

Thank you,


Same thing happened to me in 2019-2020

I had the same thing happen to me which even brought me to the hospital... eventually Dr found out what was causing my heart rate to spike out of no where... Lyme disease.

which I was treated for and now no longer have symptoms. So as you can see even a simply illness of some sort can affect heart rate for pacemaker patients... it doesn't have to be the device itself. Either way.. speaking with all doctors to check all possibilities can help.


I would ask for long term monitoring Hayden

Hayden, as an arrhythmia sufferer I know only too well the symptoms you are experiencing, particularly the extreme tiredness which can be present during surges in rhythm disturbances.  

Looking at your heart rate, 95 bpm would still be in the normal range, with anything over 100 bpm being a tachycardia, although if the rhythm were irregular, it could definitely be causing some of the symptoms you describe.

I would recommend that you ask for longer term monitoring to try to identify the rhythm disturbance present, since with a normal heart rate you shouldn't be feeling shaky, dizzy, weak and tired.  

Christmas time can be a period of heightened emotions, perhaps sadness for those you have lost.  There may be several reasons for an increase in your palpitations but it is worth asking for some checks, perhaps electrolytes and anaemia again?

Are you just sitting still at 65 then it does go to 95 ?

Thank you

Yes, i am just sitting and it'll go to 95 randomly, and stay that way until i go too sleep. I feel quite shaky and weak and tired when this happens. 

I have an appointment on tuesday so i will bring this up,

I also find after eating my hr will go up quite a lot, and again not slow down until i go too sleep. 


Thank you,
