Creating an environment devoted to this purpose has enabled us to provide everything needed for the best patient outcomes in one place.
The center enables leading cardiac electrophysiologists and cardiovascular surgeons to collaborate with a team of specially trained professionals, including a clinical nurse specialist, cardiac anesthesiologists, registered nurses, and technicians with special training in electrophysiology procedures.
Using state-of-the-art equipment, these professionals perform many procedures previously available only at leading academic medical centers. These include the most technologically advanced computer assisted diagnostic electrophysiology studies and catheter ablation procedures, as well as, the expert implantation of pacemakers, defibrillators and cardiac resynchronization devices.
Treating Disorders of the Heart's Electrical System
Normally, electricity flows throughout the heart in a regular, measured pattern. Problems can develop anywhere along the electrical pathways, disrupting the regular beating of the heart and causing an abnormal heart rhythm, or arrhythmia. Left untreated, arrhythmias can lead to serious consequences such as heart failure or sudden cardiac death, two leading causes of death in the U.S.
A comprehensive medical examination and special tests help cardiac electrophysiologists – cardiologists with advanced training in the diagnosis and treatment of arrhythmias – properly identify the rhythm problem. The treatment that best matches the individual needs of the patient can then be determined.
The most common form of arrhythmia, atrial fibrillation, is an irregular heart rhythm originating in the upper chambers (atria) of the heart in which the heart’s electrical system causes the atria to quiver, or fibrillate. The quivering upsets the normal rhythm between the atria and the lower chambers (ventricles) of the heart, hindering the heart's ability to pump blood and depriving the body of oxygen and nutrients.
While atrial fibrillation can be treated with minimally invasive surgery, it is important to have the condition diagnosed as quickly as possible.
The Cardiac Rhythm Center features specialized equipment designed to assist physicians during complex electrophysiology studies. These include:
- Computerized heart monitoring systems that provide exceptional EKG recordings during electrophysiology studies and ablations. These systems reduce procedure times and enhance diagnostic capabilities.
- Two separate computer-assisted 3-D mapping systems which are used to locate and guide treatment of the most complex arrhythmias. Each system has unique capabilities that allow our electrophysiologists to select the best technology to diagnose and treat arrhythmias with greater accuracy and precision.
- Cardiac echocardiography that uses ultrasound technology to visualize the anatomy and physiology of the heart and measure blood flow from within the heart chambers. Images are transmitted via a steerable, ultrasound tipped catheter that is positioned inside the heart during certain procedures, such as ablation procedures for atrial fibrillation.
Full Range of Treatment Options for Arrhythmias
Radiofrequency (heat) Ablation is commonly used. It is a non-surgical procedure using small catheters in the heart to cauterize minute portions of the heart tissue that may be causing the arrhythmia.
Cooled-tip Radiofrequency Ablation allows the use of higher power to produce larger and deeper lesions when needed for the elimination of certain arrhythmias.
Cryoablation or freezing technology is a new ablation option that delivers extreme cold, rather than heat, to treat abnormal tissue. Cryoablation can further enhance the safety of ablation of some higher risk arrhythmias.
Surgical Treatment of Arrhythmias
Performed on our Concord campus, surgical treatment of atrial fibrillation, including minimally invasive surgical approaches, is also available.
