Hi, @donsmith1959 - welcome to Mayo Clinic Connect. I apologize for the delayed response. Thanks for the information on your diagnosis with PVCs three years back, how they go away while running, and how you woke up a few nights ago with fluttering similar to what you've experienced when hot-weather running. Sounds like though your doctor has indicated you are fine and not recommended a cardiologist, you have some questions about this occurrence.

Here is some Mayo Clinic information on PVCs you may be interested to read https://www.mayoclinic.org/diseases-conditions/premature-ventricular-contractions/symptoms-causes/syc-20376757.

I'd like to tag @pantherfancm77 @tigertoo @jameck @eileena @balubeje for their insights on your situation.

Have you experienced PVCs in any other specific conditions, @donsmith1959? Is awakening with fluttering something you've experienced before?

See if you can have your doctor hook you up on a 30 day monitor. Then you can see what is going on when you feel the fluttering. You could also do a 24 or 48 hour holiter monitor if it happens every day.

Once again, if your heart is healthy PVC's are totally benign!

The first step is usually a 24 hour holter monitor. They will note the average number of PVCs by hour, as well as whether they might be coming from one or several areas.

Get a 12 lead, not one with fewer leads as they can see more based on the 12. And keep those results with you. Even if you are ok, it’s a good baseline.

I had a certain PVC for 20 years. At the base of the papillary muscle that attaches to the Mitral Valve. Used to drive me crazy. A few good burns from an ablation killed that little monster
