Stopped: With the current health situation, we do not anticipate a significant resumption of recruitment for several months.
Cardiac Resynchronization Therapy (CRT) is an established treatment for patients with systolic heart failure and bundle branch block, improving functional capacity, quality of life and reducing morbi-mortality. Adjusting atrio-ventricular (AV) delay, vector optimization and choice of different modes of stimulation can influence the acute hemodynamical consequences of CRT but also its medium-term and long-term clinical and echocardiographic effects. The aim of the present prospective study is to investigate whether the different stimulation modes lead to different acute hemodynamic response, by evaluating the highest systolic pressure using the Finapress ® method.
