High resting heart rate averaging 100 bpm

I was going to reply about my Apple watch and Polar chest strap, but I find I'm out of date. This web site seems to be good on describing the options.

When my resting heart rates were at 100 or more, I was in persistent Afib which was treated with cardioversion. This is not medical advice, just telling you my experience with a high resting HR.

Many thanks for your reply! Perhaps my cardiologist will detect an issue, but I don't have an appt yet. I do have a KardioMobile device that I use to check my potential Afib. It consists of a finger pad connected via my iPhone amd the app. So, every time I've checked I never have showed Afib. I drank a lot of water yesterday and got my BPM down to 80 for a few hours. When I woke up and checked it this AM, it was back up to 109 BPM. Ugh!

There are various potential causes. Electrolyte defect, dehydration, poor kidney function, hyperthyroidism, or tachyarrhythmia as examples. A rate that high, even up to 99 BPM, is technically NOT tachycardia, but it COULD BE for you. You need to be checked out because only a very small percentage of the average adult population would have a 'normal' heart rate above 90 BPM.

@deniseheart "Cardioversion is a medical treatment that uses quick, low-energy shocks to restore a regular heart rhythm. It's used to treat some types of irregular heartbeats, called arrhythmias. An example is atrial fibrillation (AFib). Sometimes cardioversion is done using medicines.
Cardioversion is usually a scheduled appointment but is sometimes done as an emergency treatment. Usually, cardioversion quickly resets the heart rhythm.
Cardioversion is not the same as defibrillation. That's an emergency procedure that's done when the heart stops or quivers uselessly.

Yes, I know. I mentioned in my post that I had persistent Afib.

I completely agree with you AFIB can really affect the heart rate. I was told many times the ventricles will try to match the atrial.

I have an ICD/Pacemaker for over 20 years. I have been through so many shocks, issues, hospitalization it would take a page just to list them. I just got out of hospital where they were trying to find cause on VTAC.

I do know that my doctors were very attuned to my thyroid. I think @laughlin1947 should asked his doctors to test it as if high. Along with informing all medicines and supplements on. I have done this many times and just went through a visit with pharmacist who when over every medication and supplements I was taking. She had me come of so many supplements I had no idea they were affecting my medications. She also went over times to take and if with food, etc. I learn a lot form that visit which lasted one hour.

Many things can cause a high resting pulse rate and can be a trial and error journey to find the cause.

Note that the sample size was adequate for empirical factoring, although not as robust as many would like it. Of that sample, under 2% were assessed as having IST (Inappropriate Sinus Tachycardia), meaning it was just a fast heart rate, not technically an 'arrhythmia', and the average was a whopping 94 BPM. None of them, in follow-up or at the time of assessment, showed deleterious heart morphology changes

I've just been looking up normal resting heart rates. Various resources all say a resting HR of between 60 and 100 is normal. However, 100 seems high to me (I'm not a medical professional!) if you are active, not overweight and have no other health issues.

I had an ablation 3 weeks ago, and my resting HR has risen, or at least is unstable. Sitting on the couch the other night, when I would expect a HR of around 60, it was stuck at 109! However, I'm trying to be patient, as this is the "blanking" period after an ablation when the heart is adjusting. I do try breathing and relaxation exercises to bring it down, but that isn't always effective.

Hi there, just had PFA on May 29. I use Kardia, SPO2 monitor and a ring device, as well as periodic BP testing. All four of the devices are relatively close in the BPM category. My RingConn 3 records continuously and reports a current bpm or a 5 min high/low rate or a 30 min hi/lo. Hope this helps. BTW, my HR was mid 50’s and just couldn’t get above 80 with exertion. Today I am averaging mid 80’s at rest. Can get up to 120’s with exertion. Doc cut metoprolol from 50 mg to 25 mg
