Electrophysiology and Pacing Program

Pediatric cardiac electrophysiology is the evaluation and management of the disorders of electrical conduction system of the heart in infants, children and adolescents. Normal function of the electrical conducting system is required to maintain adequate contraction of the heart at an appropriate rate. Abnormalities of the electrical conduction system can result in arrhythmias. Arrhythmias comprise irregular heart rhythms and inappropriately rapid or slow heart rates. Symptoms of arrhythmias may include palpitations, lightheadedness, weakness, fatigue, syncope or cardiac arrest.

Electrophysiology Clinical Services

As a part of the Arkansas Children's Hospital (ACH) Heart Center, the electrophysiology program offers a variety of clinical services, including inpatient and outpatient care. Specific services offered by the Electrophysiology team can be invasive or non-invasive and include the following:

Invasive Services

  • Pacemakers and Implantable Cardiac Defibrillators (ICDs) implantation into the heart and veins.
  • Subcutaneous Implantable Cardiac Defibrillators (S-ICD) is a newer technology and is implanted without using the veins or going inside the heart.
  • Invasive electrophysiology study and ablation procedures for supraventricular tachycardia and ventricular tachycardia or other arrhythmias are performed in a dedicated cardiac electrophysiology catheterization lab. In ACH about 125 procedures are performed annually.
  • Implantable Loop Recorders (ILR) implant and monitoring- ILRs monitor the heart continuously to evaluate for arrhythmias.

Non-invasive Services

  • Follow up and management of patients with implanted devices in specialty clinics.
  • Holter monitoring, electrocardiograms, remote event monitoring and implantable loop recorder evaluations for arrhythmias
  • Medication challenge for certain arrhythmias including Procainamide and Epinephrine challenge tests.
  • Genetic testing, family evaluation and counseling for various arrhythmias substrate including long QT, hypertrophic cardiomyopathy, etc.
