The [[Heart Rhythm Society]], founded in 1979, promotes education and advocacy for cardiac arrhythmia professionals (including cardiac electrophysiologists) and patients. It is the largest society in the field.
A brand-name medical system used in [[cardiac electrophysiology]] is called produced by Biosense-Webster, a subsidiary of [[Johnson & Johnson]], andproduces isa cardiac electrophysiology system called CARTO.<ref name=Macias2016/> The system is designed to visualise the real-time calculated position and orientation of a specialised [[RF ablation]] [[catheter]] within the patient’s heart in order to minimise [[Ionizing radiation|radiation exposure]] during [[fluoroscopy]], increase the accuracy of targeted RF ablation and reacquisition of [[cardiac pacing|pacing]] sites for re-[[ablation]].<ref>{{cite journal|last1=Jaïs|first1=P|last2=Weerasooriya|first2=R|last3=Shah|first3=DC|last4=Hocini|first4=M|last5=Macle|first5=L|last6=Choi|first6=KJ|last7=Scavee|first7=C|last8=Haïssaguerre|first8=M|last9=Clémenty|first9=J|title=Ablation therapy for atrial fibrillation (AF): past, present and future.|journal=Cardiovascular research|date=May 2002|volume=54|issue=2|pages=337-46|pmid=12062339}}</ref> Its navigation system calculates the position and orientation of the catheter tip, using three known magnetic sources as references. The system uses [[static magnetic field]]s that are calibrated and computer controlled. Due to the nature of magnetic fields, the orientation may also be calculated while the tip is stationary. By calculating the strength and orientation of the magnetic fields at a given location, the x,y,z position may be calculated along with the [[Roll, pitch, and yaw|roll, pitch, yaw]] orientation.<ref name=Macias2016>{{cite book|last1=Macias|first1=Carlos|last2=Ajijola|first2=Olujimi|last3=Shivkumar|first3=Kalyanam|last4=Buch|first4=Eric|editor1-last=Steinberg|editor1-first=Jonathan S.|editor2-last=Jais|editor2-first=Pierre|editor3-last=Calkins|editor3-first=Hugh|title=Practical Guide to Catheter Ablation of Atrial Fibrillation|date=2016|publisher=Wiley-Blackwell|isbn=9781118658505|pages=65-73|edition=2nd edition|language=English|chapter=Chapter 7: Electroanatomic mapping systems}}</ref>
