A few months ago a close friend of mine began having having what she describes as a skipped heartbeat , then sometimes returning to a more regular heartbeat while at other times skipped heartbeat with a fluttering And or skipped heartbeats a few more times in a row. These symptoms happen either a few minutes after eating or after eating then walking ( with most symptoms occurring after eating. There has been also a slight lightheaded ness with flushing reported only once or twice ; after exception or sitting. The symptoms usually last usually only a few minutes except for twice when the symtoms with one or two skipped beats every 10-15 minutes lasting intermittently for about one half hour. The symtoms just began this summer.
