More than 10 million people worldwide suffer from the life-changing effects of arrhythmias. Until recently, the only therapy options for patients were drugs and implantable devices. Technology from Endocardial Solutions is offering new potential for catheter ablation, a curative procedure in which the source of an arrhythmia is identified and eliminated with a pulse of radiofrequency energy. The EnSite 3000® system allows physicians to accurately map the heart and pinpoint the source of an arrhythmia. This technology is helping patients who previously could not be treated through conventional techniques.
