Abstract: Arrhythmia and cardiac electrophysiology services are an innovative and fast-growing branch of clinical cardiology.In the past 3 decades, electrophysiology studies and ablation of cardiac arrhythmias have become an established treatment option available to patients with arrhythmias ranging from supraventricular tachycardias and typical atrial fl utter to more complex ablations for atrial fi brillation and ventricular tachycardias.With the increased need for skilled Physicians capable of performing these procedures, the need for skilled Clinical Technologists has also increased.Suitably qualifi ed Cardiac Technologists, specialised in providing technical support for electrophysiological procedures in the EP lab, are an integral part of the arrhythmia team.Technology in the fi eld of electrophysiology is constantly developing and improving.It is the Technologist's responsibility to adapt, learn and improve their skill set to ensure they can safely perform their duties in the EP lab.The accreditation in electrophysiology for Cardiac Technologists was proposed to help ensure safe and professional standards for all Cardiac Technologists doing electrophysiology procedures.
