Electrophysiology (EP) is a branch of cardiology which helps doctors to evaluate the heart’s electrical activity and understand and locate abnormal heart rhythms. An EP study is often done to evaluate patients who have “fainted” or have experienced an abnormal rapid heart rhythm. It may also be recommended for patients who have impaired heart function and intermittent extra heartbeats. In some situations, patients with a congenital cardiac condition may need an EP study as part in order to assess their risk of developing serious arrhythmia.

Based on EP study results, the doctor then decides on the treatment, medication, catheter ablation, implantation of a pacemaker or defibrillator to manage the heart’s rhythms, or more diagnostic tests.

The following are some of the services which are provided in the Electrophysiology clinic:

  • Outpatient and inpatient consultation service
  • Invasive and non-invasive investigations for heart rhythm disorders other than electrocardiography, such as holter monitoring and extended cardiac rhythm monitors
  • Invasive electrophysiological procedures when required to diagnose arrhythmias and conduction disturbances and catheter ablation of these arrhythmias when appropriate
  • Assessment of patients with syncope (fainting) to exclude life threatening arrhythmias and genetic syndromes
  • Assessment and management of patients who require implanted cardiac rhythm devices
  • Follow up of patients with cardiac pacemakers, defibrillators or implanted loop recorders

Dr. Omar Elhag
Consultant Intervention Cardiologist

Dr. Elhag is a highly experienced interventional cardiologist who specialises in Electrophysiology. He graduated from the University of Khartoum in 1981 and underwent further training in Sudan, Saudi Arabia and the UK.

He provides a comprehensive range of electrophysiological (EP) diagnostic and therapeutic procedures. In addition to regular outpatient services he offers extensive EP consultations on all forms of EP problems for inpatients including implantation of cardiac pacemakers, ICDs and CRT/CRT-D devices, reveal devices and radiofrequency ablation.
