The world’s only wireless endocardial pacing system for cardiac resynchronisation therapy (CRT)—WiSE (Wireless Stimulation of the Endocardium) CRT System (EBR Systems)—is showing promise treating heart failure patients who have not previously responded to transvenous CRT and in those who have anatomic difficulties to access the epicardial left ventricle. The technology may also be potentially used in patients requiring an upgrade to CRT from a standard pacemaker or defibrillator.
