Premature atrial complexes origin from an ectopic pacing region in the atria. They are an example of ectopic beats. The result is a p-wave with often a different morphology as the preceding ones. A premature atrial complexe is usually followed by a compensatory pause caused by the fact that atrial depolarization enters the sinus node and resets the sinus rhythm.
