  • Does anyone know if the monitor is the same as a V1 lead and is it normal to have some downward spikes. If not V2 google says it could be enlarged ventricle or ischemia.
    Thanks

    • When worn as indicated in the User Manual, the Frontier X is a single channel bipolar ECG in the CC5 Lead position. This lead position is used in laboratory settings to measure the hearts electrical activity during exercise.

  • Hi Shocktempo.
    In my case I had slight atrial fibrillation a few years ago. Had Pfizer in June. By Oct 3rd I was hospitalized with advanced heart failure with uncontrolled Afib and ventricular enlargement with 20 percent ejection fraction and a temporary stroke from a blood clot. . I am 59 years old. Doctors don’t know the cause. I asked about t…Read More

    • Had issues with SVT before the vaccine but only after having covid, although scary my heart was always in sinus rhythm. Things were settling down so had the Pfizer jab and about 2 months later collapsed in the street with fast AF resulting in a cardio version. Struggled then with numerous ectopics. Started to feel a little better and had the…Read More

    • Yes. No heart issue prior to vaccine. A few weeks after first Moderna vaccine I had a 100% RCA blockage caused by a clot. Clot led to a STEMI. All other coronary arteries were completely clear of any plaque etc. ambulance too 5 hours so the STEMI caused quite a bit of cardiac damage that I’m now learning to live with.

    • I was diagnosed with AFIB a number of years ago. I would end up with a very fast heart beat around 170bpm. I never converted out on my own – always a cardio version. As such I have had two ablations, the original one in July 2018 and the last one (more of a touch up) in August 2021. I had COVID in April 2020 and had both Pfizer shots and booster…Read More

    • 46 male, athletic. For me, I had normal LP-a. 2 weeks after my second Moderna shot, I noted a greatly elevated LP-a. I took it several times after that, and it slowly declined back to normal after a few months. Sometime after that. I started to have some chest pains. The cardiologist, did a CAC, which was clean. I bought this device as he…Read More

    • Not ruling out the vaccine as a cause, but I’d also be looking as what else I might have changed? New meds/supplements/coffee brand and intake/etc. There’s no experimental control.

    • Hi, Patrik from Sweden here. I am also 59 years okd. I dont have your story but got Pericardit after the vaccin, in July. Just getting back in the saddle w training.

      • Hi have a past history of atrial fibrillation (54 yrs of age). My first dose was Astra Zeneca and second dose Moderna. In both cases didn’t have any issues with arrhytmias or atrial fibrillation. Will receive my booster shot next week (will most likely be Moderna or Pfizer). If I have any issues, will update.

    • Thanks for sharing your story. I had similar problems after the second Pfiser vaccine. I also started having arrythmias and I also had gastrointestinal inflammation which caused me to go into a SIBO flare which I never knew I had SIBO. I also purchased this device so that I could monitor the PAC’s that I have. I have had an echo and a cardiac…Read More

    • Interesting to read all of these experiences around the vaccine. I’m a 38 year old female. I had a cardiac ablation done in 2019 (to treat SVT). I developed PVC’s in 2020, which have progressed to bigeminy/trigeminy beats. I had Pfizer vaccines x 2 – but I can’t say the vaccines made anything better or worse because I was having these issues…Read More

      • Daylene-any updates? Post vax and then getting the virus I have been getting big HR ‘drops’ when riding above threshold. Stress test normal but had PVC couplets at high end of test. Have been using Polar HR10 and assume that it is showing PVCs as lower HR or is my HR actually lower? Recover quickly but got Frontier to capture. Cardiologist(s)…Read More

    • I had hypertension since few years and was on medication since 2019. I had asymptomatic covid in jul 2020. I trained hard and did an event of 100km on 2 Oct 2020. 6 weeks later i had my HA, with 99% blocked LAD. Placed a stent and my training resumed a month after heeling of deep cut to my foot in a freek accident in Feb 2021. I ran a marathon to…Read More

    • Hi Shocktempo, I have a slightly different story to yours. I was diagnosed with Atrial flutter 7 years ago that was “cured” by an ablation procedure. Last summer a regular health check up picked up A Fin that I am now being treated for. I had a completely unexpected TIA stroke on Christmas Day and recently purchased the frontier X as a way of con…Read More
