It could be related to BP, although mines not. When my BP was 180/126 it didn't happen, but happens when BP is normal. But if you do have any other symptoms always worth having it checked out.

Anila- I have palpitations or ectopic beats all the time too. Drives me mental. It's worse when i'm sick or pregnant, but it feels like my heart is doing somersaults in my chest. Sure gives nurses a fright when they hook me up to a monitor or take my pulse.
