Cardiac resynchronisation therapy in heart failure

Cardiac resynchronization therapy [CRT] represents one of the recent advances in heart failure [HF] management. It implies an attempt to establish left ventricular synchronous contraction in order to improve left ventricular hemodynamics; thereby improving functional class, and quality of life. CRT has come a long way from an incidental treatment modality to an accepted and indicated treatment strategy for patients suffering from severe and chronic heart failure. With its ever increasing use, it is important that we become conversant with its role in the management of heart failure. This article aims to review the evidence for CRT, how CRT benefits patients of heart failure and reveals the indications of CRT implantation in HF patients
