Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

Despite the fact that there is no consensus on the clinical impact of optimizing cardiac resynchronization devices, echocardiography is currently the most used method to optimize the programming of the device in the absence of other well validated methodology. On the other hand, while the role of cardiac imaging in the selection of candidates for cardiac resynchronization therapy remains controversial, it is well established that imaging is essential to establish an objective evidence of response to the therapy. In the present chapter, the role of cardiac imaging in optimizing the programming of CRT devices as well as of the usefulness in the follow-up of patients treated with CRT will be discussed.
