WitrynaThe term ectopic focus means: (1). ectopic, the electrical signal originates from a different location other than the SA node, and (2). focus, the site where the electrical signal originates from. This ectopic pacemaker can self-generate an electrical signal that can either cause an early beat or can continually pace the heart.
