I have a pacemaker due to a fib. . It feels so good to go to a gym again . Salute to you .

Thank you for sharing about your use of the Lookee tech products (veyr interesting), especially during exercise. I use two 24/7 continuous ECG monitoring tech products: Fourth Frontier 2x & the Wellue Heart Health Monitor--& both can be worn continuously (& during exercise). The Fourth Frontier package can be set to be worn continuously for several days at a time.

I consider both essential to my understanding of my post-C19 mRNA vaccine-injured heart, which if it were not for my FitBit Charge 4 atrial fibrillation notifications...on the 4th day after receiving the Moderna bivalent mRNA vaccine "booster," I would have not known about & known that I need to obtain...medical diagnosis--acute autoimmune myocarditis (diagnosed via a cardiac troponin blood assay... with elevated troponin I (cTnI)).

As we know from the burgeoning peer-reviewed scientific literature, including the recent Swiss study (University of Basel Cardiology and Cardiovascular Research Institute ), Buergin, Lopez-Ayala et al., the risk for post-C19 mRNA vaccine acute autoimmune myocarditis may run as high as...1 in 35, which is orders of magnitude greater than the risk outlined in the CDC-FDA VAERS data/reporting. Interesting how much of this burgeoning C19 mRNA vaccine-induced myocarditis peer-reviewed literature is...conducted outside of the United States.

For my part, I wear the Fourth Frontier 2x chest-strapped monitor when I exercise, as it records & presents a range of very useful data, such as a metric it terms "Training Load," duration of exercise, percentage of normal sinus rhythm, percentage of "other" heart rhythms (arrhythmias), "noisy" rhythms (those not able to be assessed), heart rate zones, heart rate, heart strain (very important given my myocarditis injury), body shock, breathing rate, HRV, & step cadence).

On the other hand, I wear my Wellue 24/7 continuous heart monitor for up 24 hours at a time (it can record up to 24 hours of continuous ECG before it starts recording over the data recorded in the previous 24 hours). The Wellue tech also includes an old-school Windows-based software package that prepares an incredible, exercise-cardiologist-quality ECG/EKG strip & includes categorization of up to 17 different EKG/ECG events (including PACs, PVCs, PAC/PVC couplets, afib, atrial flutter, supraventricular tachycardia, ventricular tachycardia, etc.). This software then generates an incrediblly detailed & useful--& very comprehensible, report, including analyses of all the observed/recorded ECG/EKG events, which is easily as valuable as enduring an in-office exercise ECG/EKG and/or so-called "stress test"... & then getting the filtered/interpreted data results...spoken to me by a disinterested American cardiologist. With the Wellue, I have been able to share repeated 24-hour ECG/EKG recordings, analysies, & reports with consulting cardiologists (all of whom reject health-insurance payment), including one based in the UK. So in my estimation the Wellue Heart Health Monitor tech & software are...invaluable.

But I must also praise Apple Watch's "Atrial Fibrillation History" algortihm (which is APple-speak for the medical terms "Atrial Fibrillation Burden." Once set to Atrial Fibrillation History," the Apple watch measures heart thythm 24/7 & generates a once-weekly Atrial Fibrillaiton Burden report, which in both basic & clinical research is measured as the percentage of time spent in atrial fibrillaiton over (divided by) total time measured. The peer-reviewed data suggest that an Atrial Fibrillation Burden measurement of 11% or more signifies increased risk for stroke (primarily ischemic stroke).

The Apple Watch Afib Burden/History metric is a powerful & actionable metric--& I use it to get a broad handle on how I am doing & is an excellent foundation for the more-detailed Wellue & Fourth Frontier data. I also keep an Excel spread sheet of 37 different variables, which I attempt to model using correlational & low-level regression models, to identify patterns among/between the 37 "lifestyle" (including diet, G.I. factors, hydration, electrolyte intake, & other variables)...to help me predict & manage ectopic heart beats & onset atrial fibrillation.

Great to hear that you have returned to exercising & clawed back elements of your prior life--& gotten off the anticoagulants & pacing medications. Good on you!

Stay safe & all the best 🙂
