Hello, in the past week I have had an onslaught of Pacs, I know that it is because I got them captured at the err room. They started all of a sudden. I get them when standing up, go for a mild walk on treadmill, sleeping on stomach yawning standing in the sun, taking a shower. Almost everything it seems. Once again doctor s are telling me anxiety. I had a stress echo a year and a half ago with good readings. But maybe I have a clog in an artery I'm telling myself now. It has been ongoing now for 5 days. The day before I got on the treadmill for 30 minutes on a likelihood and nothing. Then the next day it hit me hard. I'm wondering if the sudden onset and frequently is justifiably alarming or if it will pass. Or maybe I have to get a new echo
