Does the HRM Dual have issues with irregular heartbeats like PAC & PVC?

I'm 70 years old and used Garmin HRMs for decades. Had AFIB starting in my 40s through my 60s and never lost HR data when the AFIB would kick in. I would see HR jump from the 140s to the 220s. For other reasons I've been off the bike for a few years but now have about 30 days on it. I had an ablation nearly 2 years ago and so far no AFIB events. OTOH, I occasionally have Premature Ventricular and Premature Atrial contractions (PVC/PAC). I can usually feel a slight flutter when I am in PVC/PAC. This is usually transient and no impact on my rides. The cardiologist doesn't see these as being too dangerous.

So...since I've gotten back on the bike I normally get good connectivity with the HRM Dual and Edge 840. I do all the tricks of wetting the electrodes and later getting warm enough to have sweat under the strap. I'm going easy in Zone 2 for now and things going well then I lose the HR data. Doing all the normal tricks (making sure the electrodes are wet, checking position...) I might get HR data for a few seconds but once I got going it would stop. I usually had to complete my ride without HR data. BTW...my apple watch would give me HR data.

I did try the reset procedure tonight and so haven't had a chance to see if that did anything. If not...

Any suggestions for other HRM straps to try as an alternative? Any other thoughts?

I have no problems with the HRM Dual, although I have PVC. I only run, but I guess the bike should be fine too. It looks like something is wrong with the strap, isn't it old?

Sadly nope. I actually replaced my "old" one a month ago and at the same time upgraded my bike computer to the Edge 840. The problem continued. SIGH. BTW...no difference between the old and new strap.

Maybe you have both the ANT+ and BLE variants of the HRM-Dual sensor defined on your Edge? In that case, set tbe BLE one to Off. ANT+ is generally easier in a technical sense, it just broadcasts, less things that can go wrong in the communication.

Is the battery in the Dual OK?

Can you check with a phone app and the BLE connection of the HRM-Dual, look what it is sending while you are sitting down, and when walking around. HRM sensors don't often break, unless you drop them on a hard surface, but sometimes components can just fail.
