Good echo result recently had 24 holter few yrs back odd svt ectopic beat.fast irregular many beats crammed in 10 seconds is this svt i get sometimes?

As I indicated in: your previous question, the arrhythmia cannot be accurately diagnosed by physical examination (pulse) when it is so short in duration. You need some form of electrocardiographic monitoring to make a diagnosis. With a normal echo it is unlikely to be anything too worrisome but could be afib. Get it checked out by your local health care provider.
