In the last hour or so Ive had 7 or 8 ectopic beats (I think!)

It's really wierd like there's something wrong. I went for a walk to see if it would help but they seemd to come every few mins then, so came home.

Is this harmless?? Never had them as much in a short space of time like this.

Im really worried to be honest.

My heart rate is fine (in the 60's) so I dont get it.
