  • As a 73 year old male , spinning for 19 years , with a double bypass and nine cardiac stents ( symptom free) are my effort and strain metrics the same as a 25 year old ? I am sucking at 150 BPM but the strain measurement barely budges. Comments ?

  • I recently had a second ablation surgery, this time for AFIB on my left ventricle. The first time was 5 years ago for atrial flutter. I’m a runner/triathlete and was able to start training again after the a-flutter and within a few months back run a 1:28 half (age 55). This year is much harder. The AFIB was much worse than the a-flutter, and…Read More

  • Hi! I’m interested in the effect of body shock on Atrial fibrillation in runners. I have read several reports on exercise induced Afib by endurance athletes, there is an indication that running has a greater impact. I noticed that my HR was affected more running on hard surfaces. On getting fourth frontierx I tested this and there was a definite…Read More

  • It was suggested that in cold weather, anti-static spray could improve the signal quality. There are various types of anti-static sprays, which are being suggested? (Industrial, clothing, electronic…etc.)

    • I cycle at altitude in low humidity on a regular basis and had serious issues with signal quality – particularly when going downhill at high speeds. I have largely solved the problem by using a combination of Spectra 360 Electrode Gel and industrial anti-static spray called ACL Staticide 2003 – both inexpensive on Amazon. For the static spray I…Read More
