The aim of the study was to evaluate echocardiographic changes in clinical responders and nonresponders after 3 and 15 months of cardiac resynchronization therapy (CRT). In the group of responders significant changes of most monitored echocardiographic parameters were observed 3 months after CRT implantation.
The only parameters which changed significantly only after 15 months were the systolic function of RV and the decrease of the RV size. In the group of nonresponders these changes were not observed.
