Summary

Study Purpose and Rationale The purpose of this study is to evaluate the lung Doppler signals changes during cardiac resynchronization procedure. As the LDS represent the various mechanical events of cardiac origin it is assumed that they may reflect the relative timing between contraction of the ventricles and atria and thus serve for effective synchronization of these activities. Aim of the study: The aim of the study is to assess whether the changes in Lung Doppler Signal (LDS) waves' characteristics will mimic the changes in echocardiographic parameters designed to assess diastolic inflow and systolic flow in patients undergoing Echo-based CRT optimization.
