I had a Cryo ablation 4 week and currently on beta blockers . Resting heart rate 65/72 and when walking doesn’t go much higher.
In bed last night woken up after about 3 hrs and heart rate was 102 it went down and stayed in 80s for sometime . Never happened before even prior to the ablation.
You are still healing. This sort of thing happens for the first three to six months.
Hello kalgs, hope you are feeling generally OK. As mentioned in the factsheet, heart rates often increase after an ablation and sometimes it can take a while before they settle back to norm. I guess it’s also possible that dreaming can cause rates to increase even though it’s not unusual for folk to be unaware they have experienced a dream. It’s still early days so changes in the way your heart functions are likely to occur for some while yet………
Thanks for your reply. What worries me is that it’s not happened before. I could see my Kardia going up like a Speedo. In fact I went back to sleep and was woken up again later but my pulse was not quite as high. I had been dreaming on both occasions
I understand that kalgs, but as far as I know, you haven’t had an ablation before either……
Lucky you. Your recovery has actually been very good so far kalgs from what you have posted so don't knock it. No doubt you'll still have a few surprises .
There your possible answer. You'd been in sleep mode (I think it's REM when we dream), you woke up and your metabolic rate went up suddenly. Happens to me too. Dr Google doesn't always help us but if you do a sensible search you'll find interesting stuff on our metabolic rates during different activities. The heart responds to these and yours is simply adjusting. Regard it as a positive.
I can't add to the other comments Kalgs - give it time 
Paul
Thanks Paul
No worries Kalgs. You'll get there - I feel sure of this. Slowly slowly does it
Good luck - keep us updated on the forum. You have gone through the bad bit. The plane has taken off and is in the air now. It will land soon.
Have a lovely day.
Paul
So kind
Heart’s got to punish you somehow if it’s not allowed AF 😀
Morning Kalgs, what you are telling us sounds pretty normal to me - perfect even! For some of us (me included) just checking what your pulse is doing can cause anxiety and take it up. I've stopped checking now and feel better for it. Now if I felt ill and knew my heart was racing that would be when I'd check. I used to use a stethoscope too if my BP machine wouldn't work because of AF.
The most important thing is, how are you feeling now? Still a little worn out I would guess.
Let us know how you get on please. All is looking good.
Jean
Thanks for the kind reply . It woke me up twice . Must admit it’s tired me a bit today
I agree with Bob. Expect the unexpected! I never had night events pre ablation - had three in the weeks following. Don't get them now. And although I've got my name down for a touch up (won't repeat my story) I still feel changes. Random migraine aura yesterday - seeing stars for about 5 minutes. All I did was lean over to my right to pick something up. No AF, no dizziness, carried on with my Zoom teaching, after a while it went.
I have had 2. It can take up to 3 months to stabilize and stay in NSR. I am sure the cardiologist would have explained this. It was the same with me.
Hi Kalgs, similar story to yourself. l wake up quite often with a fast heart rate although l am now 9 months post ablation. Had a few hours of AF again over the weekend.. still hoping my heart will settle down. Take care.
Was the AF this first since ablation
Interesting how reliant we are these days on various monitoring devices like Kardia and Apple watches. When I had my ablations in 2015 and 2016 I relied on what my body was telling me and checking my pulse with my fingers - I knew practically instantly when I was going into AF and when reverting to NSR and although I now have an Apple Watch I still do. That’s not to say I don’t find the watch an excellent piece of kit - especially for ECGs to my arrhythmia nurse- but I do tend to check it too often. Until 2019 when I got the watch I had no idea what what my HR was - and I’ve had PAF since 2010!
In this case accurate
Not disputing the accuracy kalgs - just saying, possibly not vey well, that our reliance and use of the technology can gradually replace our natural ability to know something is not quite right and our response to it. My Apple Watch can tell me what my HR is at any given time and can show patterns on my IPhone app. Yes great but I also believe that constant checks can, and does, indicate levels of anxiety about our condition which is unhealthy. At 74 I want to get on with my life as much as possible and not keep reminding myself I’ve got AF - at the moment it’s 50/50 and that needs to improve.
Take care and good luck.
Hope you are feeling ok again - best wishes for the next few months 
My first few weeks after the ablation were fine, but then I started to hit the 'bumps in the road', and had some very bad (and long!) sessions. I've been good now for about two weeks (just over three months since the op.), but I've stopped expecting a full recovery yet.
I'm sure it's related to your ablation -- your heart will do strange things at first as it heals. Just keep an eye on it and if things get out of hand then best to contact your EP.
Good advice
Hi Kalgs thanks for your input. The watch for hr says my resting rate is about 60. Walking does raise mine and when I was at the supervised gym class last week I appeared to be happy at 125 on the trekker machine. The graph of my sleep pattern also goes up sometimes as high as 150, I am trying to cross match that with my sleep pattern to see what is going on. The only thing is I have vivid dreams and thing that might be the cause. The only drugs I am on is a rate/rythem tablet morning then one in the evening plus my Rivaoxaban. Good luck
