Mayo Clinic's approach
At Mayo Clinic, experts in heart rhythm problems provide compassionate, whole-person care to people undergoing an EP study.
A collaborative approach to care
An EP study is done by heart specialists (cardiologists) with special training in heart rhythm disorders (electrophysiologists). Mayo Clinic has one of the largest electrophysiology practices, with 30 specialists working in the Electrophysiology Laboratory.
Electrophysiologists work closely with other experts, including cardiologists and cardiac surgeons, in the Heart Rhythm Clinic to understand your heart condition and recommend the treatment options that will work best for you. This team approach helps ensure you receive exactly the care you need.
Doctors trained in treating children with heart conditions (pediatric cardiologists) work with a team of experts to care for children with arrhythmias at Mayo Clinic's campus in Minnesota.
The most advanced diagnostic systems
Mayo Clinic doctors performing EP studies have the latest and most advanced technology available to understand your condition.
The experienced staff uses advanced mapping systems, including multielectrode mapping and 3-D heart mapping. If you're undergoing cardiac ablation, these technologies help your care team accurately determine where to apply the ablation in order to give the greatest chance for success. Mapping with imaging technologies such as an MRI and intracardiac echocardiography reduces your exposure to radiation.
For people with arrhythmia who will undergo cardiac ablation procedures, Mayo Clinic doctors use radiofrequency energy and cryoablation. Energy is applied using the latest innovations in treatment catheters and technology, including balloon catheters and robotic catheter ablation.
Expertise in all arrhythmias, including rare and difficult cases
Mayo Clinic doctors have used EP studies to diagnose and treat a variety of arrhythmia types, including types that are very rare and those that are difficult to treat.
Mayo Clinic experts specialize in treating:
- Complex atrial arrhythmias
- Complex ventricular arrhythmias
- Cardiac ablation in people who have undergone the procedure previously
- Ablation for adults and children with congenital heart disease
Experience you can trust
Mayo Clinic heart specialists have extensive experience diagnosing and treating all types of heart arrhythmias, including very rare types.
Your Mayo Clinic care team is experienced in using cardiac ablation to treat arrhythmia and performs many procedures. Each year, about 1,500 people undergo cardiac ablation at Mayo Clinic.
Studies show there is a reduced risk of complications from cardiac ablation when the procedure is performed by an experienced electrophysiologist in a hospital that performs many procedures.
