Annotation of the local electrograms is important for accurate definition of the arrhythmia circuit for reentrant tachycardias and for identifying origins of focal arrhythmias. Approaches to accurate annotation require an understanding of the genesis of electrograms and their limitations that facilitates recognition of far-field electrograms and informs approaches to identify likely local activation time. Review of annotated electrograms is important when mapping produces a confusing activation sequence.
