I am experiencing skipped beats (ectopic) which appear to be related to gas and abdominal rumblings. I have undergone many tests. Can you help?

It is possible that your skipped beats are related to intestinal gas; however it is also likely that it is related to hunger, or need to have something to eat, or thirst. Often palpitations or the perception of heat beats can be treated by drinking water. So would try drinking water, either room temperature or cool when you have the skipped beats.
