Key result
No single modality from ECG to invasive mapping universally assesses cardiac dyssynchrony.
Why the study?
Despite various options for assessing electrical and mechanical cardiac dyssynchrony, no method has yet become universal or capable of answering all questions.
The assessment of cardiac dyssynchrony for cardiac resynchronization therapy remains a multifaceted process without a single universal method.
Multiple modalities should guide CRT dyssynchrony assessment; leaves open standardization of an optimal method.
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.

Zubarev et al. (2024) conducted a review in Cardiac dyssynchrony. Dyssynchrony imaging and assessment methods was evaluated. Methods for assessing electrical and mechanical cardiac dyssynchrony remain multifaceted, as no single modality from 12-lead ECG to invasive mapping has become universally applicable.
