Reversible complete left bundle branch block and a wide QRS complex following administration of sodium-glucose cotransporter-2 inhibitor and volume reduction in a patient with systolic heart failure: a case report.

ABSTRACT:

Background

Guidelines recommend optimal medical therapy before cardiac resynchronization therapy (CRT) implantation. Herein, we report the potential effect of sodium-glucose cotransporter-2 inhibitors (SGLT2is) in improving the QRS duration and volume reduction in a patient with complete left bundle branch block (CLBBB) and reduced cardiac function.

Case summary

A 68-year-old man with a history of ischaemic cardiomyopathy and decreased cardiac function had exacerbation of heart failure (HF) at an outpatient clinic. His QRS duration increased remarkably with a CLBBB of 143 ms on an electrocardiogram, and left ventricular desynchrony was assessed by echocardiography, suggesting an indication of CRT implantation. Administration of an SGLT2i and multimodal treatment for HF stabi
