Thanks for sharing this. I get fairly regular short periods of irregular heartbeat. They seem to come-&-go. (I haven't done anything about it.) Anytime I've seen a doctor for other things (which hasn't been often), and they've listened to my heart, they apparently haven't noticed anything unusual since they've never said anything. Many years ago, I was told I had a heart murmur. But it's been a very long time since anyone mentioned that. So I presume it took care of itself... which, I guess, they sometimes do.
