Impact of peak strain dispersion and septal flash on left ventricular myocardial work in patients with complete left bundle branch block

Key Points

• To evaluate how peak strain dispersion and septal flash affect myocardial work in patients with complete left bundle branch block.
• Examined patients with complete left bundle branch block
• Assessed peak strain dispersion and septal flash
• Analyzed left ventricular myocardial work metrics
• Significant relationship between peak strain dispersion and myocardial work (p<0.01)
• Presence of septal flash associated with improved myocardial work (p=0.02)
• Variations in myocardial work linked to changes in ventricular function metrics
