When someone comes to my office with concerns like this, I usually do a history and physical exam, EKG and echoardiogram. Rarely, other tests are necessary. If they are normal, this isn't something you need to worry about. PVCs are common. The degree to which they cause symptoms is variable.
If you think you are going to worry about it too much, call you doctor and talk to them about it. They may feel comfortable treating you them self or you they may send you to a specialist. In the overwhelming majority of people, this is not a problem that you need to worry about.
I hope this helps.
Thank you for your reply. It is reassuring. I've had a full medical review and the doctor is satisfied my heart is normal. I just needed a second opinion from you.
Thanks again.
