Heart rate at 138 whilst resting. Is this normal? I've got an ICD fitted for long qt


I had a ICD fitted last year for long qt syndrome. I had in infection recently and my heart rate was a bit high, the doctor referred me to the hospital and I used a cardio call monitor for a week, still waiting on any results. Today my heart rate has been 138 this morning and 101 tonight whilst resting. Is this normal? I am on Nadalo. Is 80mg. Thanks for any advice

Any time it's over 100 and you don't know why (exerting, caffeine), i would call 

Way not normal

Any resting heart rate above 100bpm is technically "tachycardia" and quite dangerous over time.  Depending on the reason, it can be serious but it sounds like you have your medical team on the hunt.  They should have ruled out the acute dangers and are looking more long range answers. Nadalo is a beta blocker so it should be bringing the rate down.  The dosage may have to be tuned to get it right.  I don't have any experience with it, so can't say much more about it.

I don't really understand the UK medical system so...  Is a "cardio call monitor" what we call a "cardiac event monitor"?  The "call monitor" is connected to the cell system at "all" times and there is a monitoring team that will call you (to get to the hospital now) if there is anything dangerously wrong? That said, I'd consider 138 "dangerously wrong" but they seem to be taking it seriously.

I wonder if your infection continues ?

Hello Jet161179,

While you are waiting for your monitor results, you could go back to your GP to check whether your infection has completely resolved?  A continuing infection somewhere could certainly cause a higher than normal heart rate.  Your doctor might want to do further blood tests to rule out continuing infection while you wait for advice from your cardiologist/EP team.  Alternatively speak to your cardiologist so that your monitor results can be reported on without delay.   

Hope your heart rate settles soon
