Overview

Cardiac resynchronization therapy (CRT) has become a big hope and an effective treatment option for patients with heart failure. Nevertheless, not all of them respond well to CRT. It is necessary to define this group of patients and identify them as non‑responders. For CRT non‑responders it is primarily necessary to arrange for adequate left ventricular stimulation as well as CRT technical parameter tuning, such as the much‑ discussed atrioventricular delay optimization. Either way, the management of CRT non‑responders also includes optimal medical therapy of heart failure and, in some indicated cases, also heart transplant.
