Septal Mapping And Resynchronisation Therapy- (SMART) Study

Normal heart function involves rhythmic contraction of all four chambers of the heart and this rhythm is maintained by the electrical wiring (conduction system) of the heart. Abnormality in this system results in either very slow or very fast heart rates leading to insufficient blood supply to the body due to inefficient pumping of the heart. cardiac resynchronization therapy pacemaker and cardiac resynchronization therapy defibrillator devices are used to synchronise heart function. The purpose of this study is not only to determine the pattern of electrical wiring of the heart and identify the variations seen in individuals with heart failure, but also, to explore the benefits of different types of pacing using CRT devices.
