Examples of septal strain pattern types. Septal strain patterns are categorized in three types: LBBB-1: double peak rebound stretch, LBBB-2: predominant stretch and LBBB-3: pseudo normal shortening, according to Leenders et al. [25] The septal strain curve is displayed as a solid black line, while the lateral wall strain curve is displayed as a dashed grey line. LBBB: left bundle branch block
