I'm 74 and have diagnosed A-Fib although it is paroxysmal not chronic and TBH I rarely experience it. In fact, intense training sessions on a cycle have apparently eliminated my need for anti-arythmic drugs. P-waves are consistently present regardless of HR , 52 (basline pulse) - 150 BPM (my set max HR). Being able to monitor this post work-out (I don't live stream) is a huge benefit. I do experience quite a bit of R to R variance on EKG. Some of this is actual PVCs that I can see on the rhythm strip. I'm told this is not pathologic; it shows up as "other" in HRV. I've also experienced some recently troubling failure of HR to accelerate on demand - just sits at around 75% max. Its occurrence is also rare but possibly indicates a developing AV block that may require an on-demand pacemaker. (I'll leave that to my cardiologist). The EKG feature has been great in keeping me clued in. I can't share it with my cardiologist because his in-hospital network won't allow it (They're in the process of changing over). I find the recommendations for next workout to be no more than boiler plate - I ignore it. Needs improvement that is relevant to my actual training load. The total workload displays are excellent allowing me to compare my cycling work-outs both on good days and bad. The weekly totals allow me to skip a work-out for recovery or, if I'm feeling it in a good way go ahead and safely press it a bit. There is no question that this is the best, most cardiovascular comprehensive wearable device I've used.

Over six months and they still have the wrong name.

I like that I get an EKG after my workout. I had a Aortic Valve replacement 4 yrs ago but still have some issues. So I track how my heart is doing. Just wish I could understand an EKG better.

This device has been a life-saver for my dad in the literal sense.. We were able to share his ECG data with his Doctor ad modify his treatment. Incredible peace of mind for me and my mom!!

Great product

The only device that can do ECG while running After a ton of research, I chose Frontier X2 (bought it on their website). Hands down the best form factor for long ECG recordings during my runs. The data quality is pretty good for a device that can record ECG during my long runs as well shorter HIIT sessions. Been looking for something like this as I enjoy long distance running and I've been worried about my heart health now that I'm in my mid 40s and have heart disease history in my family.

I have certain expectations for a portable EKG monitor, especially because I needed it for my dad who has atrial fibrillation. I have been pleasantly surprised by the Frontier X2 Portable EKG Monitor. It was packaged safely and professionally. The instructions are easy to follow. It is recommended to charge the monitor before use, but I was able to use mine straight out of the box. The size of the monitor is compact, but still offers good screen quality. The monitor also offers different leads to check. Viewing the EKG On my computer and smartphone is very easy on the Fourth Frontier Website. I used the website provided for the download. I would recommend the Frontier X2 Portable EKG Monitor. I have seen reviews which say the device has connectivity issues, but my experience is just the opposite, working very smoothly without any connection issues. This is totally worth every penny. Probably one of my best purchases ever on Amazon. It’s small, compact and accurate! Great Device

Great little device that has given me next level data on my heart health. I got it because i've been worried about my fitness and pushing my heart too far after getting covid a few times, so I wanted to get more detailed data about my heart and this is the only wearable I could find with continuous ECG. I cycle and run quite a lot so its been invaluable to know how my heart is doing and seeing the full ECG graph and other metrics like heart strain over time during my exercises has been really useful. The app UI is a little dated but overall it has more data and metrics than anything else out there which is the important thing for me because it's helped me exercise more confidently.
