Cardiovascular Care at NCH

Electrophysiology

Text/HTML

Electrophysiology (EP) specialists check the electrical activity and pathways of the heart to diagnose and repair abnormal heart rhythms. Our team's multidisciplinary approach assesses each case to determine the best plan of care - from medication treatment to more invasive options.  The process starts with a thorough EP study that localizes the area of the heart's conduction systems causing abnormal heart rhythms.  The results determine next steps:  ablation, pacemaker, implantable defibrillator or drug therapy.   

NCH is experienced in the the most advanced EP procedures including:

  • CryoAblation - a minimally-invasive procedure that uses an advanced freezing technology to address atrial fibrillation.  As the name implies, CryoAblation involves the use of a refrigerant (cryo) to ablate (or remove) electrical pathways in the heart that are conducting unwanted electrical signals.
  • Cardioversion - A brief procedure in which an electrical shock is delivered to the heart to bring abnormal heart rhythm back to a normal rhythm.
  • Complex ablation procedures - In our cardiac catheterization lab, we make use of the latest technologies, including intracardiac echocardiography and 3-dimensional mapping with the merging of CT images. This allows us to use minimally invasive techniques to treat a wide range of heart irregularities, including:  AV node irregularities, paroxysmal supraventricular tachycardia (A regular, fast, 160 to 220 beats per minute, heart rate that begins and ends suddenly), atrial flutter, and all types of ventricular tachycardia
  • New Ablation Procedure - Smart Touch Catheter - Used for complex cardiac ablation, the catheter helps to improve patient outcomes, increase safety and reduce fluoroscopy or radiation exposure. The technology enables doctors to accurately control the amount of contact force applied to the heart wall during radiofrequency catheter ablation procedures.
  • Latest cardiac devices - Each year our EP specialists implant hundreds of devices in patients who require cardiac monitoring or regulation. These include defibrillators, cardiac resynchronization devices, permanent pacemakers and implantable loop recorders.
  • Remote monitoring - The Cardiac Device Clinic provides follow-up care, both in the clinic and through convenient remote monitoring from home, to nearly 1,700 implant patients who have pacemakers and implantable defibrillators. It is located in the Cardiac Diagnostics Department on the first floor of the hospital.

Wayne tried medications and other treatments to treat his Atrial Fibrillation condition, but nothing worked. Then, he learned about an advanced treatment option at NCH called Cardiac CryoAblation. Today, he has peace of mind.
