100 Do automatic CRT optimisation algorithms work? A comparison of techniques

Introduction: At least 30% of heart failure patients who receive cardiac resynchronisation therapy (CRT) are ‘non-responders’. Optimisation of pacing intervals, referred to as CRT optimisation, is frequently undertaken in an attempt to reduce non-response and maximise the effectiveness of this therapy. Traditional approaches to CRT optimisation, however, are often expensive and time consuming. Thus, us e of automatic, device based algorithms which utilise features of the intracardiac electrogram (IEGM) for CRT optimisation provide an attractive alternative technique. The aim of this study was to assess effectiveness of these algorithms by comparison to manual CRT optimisation using non-invasive ca rdiac output monitoring (NICOM) bioreactance technology.
