Cardiac Mapping: Utility or Futility?
Indian Pacing and Electrophysiology Journal, 2002 Cardiac mapping is a broad term that covers several modes of mapping such as body surface,1 endocardial,2 and epicardial3 mapping. The recording and analysis of extracellular electrograms, reported as early as 1915, forms the basis for cardiac mapping.4 ...
