In brief: Abnormal origin

The normal pacemaker for the heart is the sinus node which is located in the upper part of the right atrium. When another site in the heart initiates the heart beat it is referred to as an ectopic pacemaker.

In brief: Outside sinus node

Normally pacemaker activity arises from a place in the heart called the sinus node.
If it comes from anywhere else in the heart it is called ectopic pacemaker. If the heart rate is adequate and the ectopic pacemaker activity arises from another area in the upper chamber of the heart it is not generally a cause for concern and is often seen in young athletic hearts.
