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.

This is an excellent piece of kit. For anyone concerned or curious about their heart’s behaviour you must consider the Frontier X. It works, has been very reliable and the app seems to get helpful updates from time to time. I don’t connect it to my watch so can’t comment on the performance of that. I had an issue shortly after I’d purchased it and they sorted it out far better than I would have expected. Some kit you buy and regret, some is mediocre, this is spot on - it does more than I expected and it does it well.

I have been using Frontier X for about ten months. Key strength of this product is the ECG recording functionality that can provide useful heart function information during exercise and rest, along with other information (heart rate, breathing rate, distance covered, etc) and a dashboard/interface that clearly communicates this information and allows the user to share it. My physician is particularly impressed with the quality of the ECG graphs.

The device has been invaluable in getting back into an exercise regime and having peace of mind after been diagnosed with a cardiac issue. This is a really great product. I would love to see some extra functions and alerts and it would be great to be able to check on the current ECG that is been recorded during a workout. It would also be great to have a shortcut button in the app for an instant ECG.

I use it with my Garmin VivoActive HR watch. Works pretty seamlessly. Data is smoother than what I get from my watch. My watch would give erratic data if the weather was cloudy. None of that problem now. When running indoors, the treadmill at my gym automatically picks up the data from this device and displays it on its screen. This is really cool. The same data can also be seen on my watch simultaneously and it gets recorded along with my workout on my watch. It takes some getting-used-to wearing the chest strap if you are not used to it. I’m very happy with this product.

I have to say, I was very sceptical about buying the Frontier X2 monitor. So far, this little monitor has been fantastic. I have Arrhythmia and use it when I feel an episode coming on. It's nice that it only takes 10 seconds to calibrate and start recording my activity. It easily syncs to the app on my iPhone via Bluetooth. All I had to do was set up an account with Frontier X and allow the monitor access to my phone's Bluetooth. Then, you just click "Connect" in the app and it finds the monitor and downloads the graphs. You can even check them out on your phone/mobile device. One of the best features is that it's easy to email and share the recordings. My Cardiologist loves that I am able to send these readings to him. I hope this monitor can help figure out what the triggers are. This device monitors your overall heart and shares various heart metrics such as HRV, Body Shock, HRM, heart strain and so much more.. I can’t end before calling out their support team. I did have a little issue setting up my account, so I emailed them. They got back to me within 45 minutes and already had the issue resolved. Then they followed up with me later that week to make sure it was still working for me. I'm in Customer Service, so I expect a lot from a company's support team. Great job!
