Dyssynchrony imaging for cardiac resynchronization therapy

The article presents an analysis of our own experience in the light of world literature on a wide range of methods for assessing electrical and mechanical cardiac dyssynchrony. Over the past decades, various options have been proposed, ranging from simple and easily performed ones, such as 12-lead electrocardiography, to more complex and expensive methods, such as invasive electroanatomical mapping. Despite promising results, none of the methods has yet become universal, capable of answering all questions. In this regard, the multifaceted process of assessing dyssynchrony continues.
