Cardiac Electrophysiology

Cardiac electrophysiology, often known as clinical cardiac electrophysiology, arrhythmia services, or electrophysiology, is a subspecialty of clinical cardiology that focuses on the investigation and management of heart rhythm problems.

Invasive (intracardiac) catheter recording of both spontaneous activity and cardiac responses to preprogrammed electrical stimulation is typically utilised to study these phenomena (PES).

These investigations are carried out to analyse complicated arrhythmias, clarify symptoms, examine aberrant electrocardiograms, determine the likelihood of future arrhythmia development, and formulate a treatment plan.Along with diagnostic and prognostic techniques, these procedures increasingly use therapeutic approaches (usually radiofrequency ablation). Other treatment approaches used in this area include implanting pacemakers and implanted cardioverter-defibrillators as well as antiarrhythmic medication therapy.The goal of the cardiac electrophysiology study (EPS) is to determine whether a given pharmacological regimen will be effective in preventing potentially fatal sustained ventricular tachycardia (VT) or ventricular fibrillation (VF) in the future by monitoring the myocardium's response to injury or cardiomyopathy.

To enable the cardiologist to choose the long-term treatment plan that best delays the onset of VT or VF after PES, a series of EPS medication trials may occasionally be required. Such research can also be done with an AICD or pacemaker that has just been installed or changed.
