SLC5A2 and hydrops fetalis: Gap junction remodelling and interstitial fibrosis have been linked to impaired electrical conduction velocity in HF.1 Here, we report a case of recovery of a wide QRS complex of complete left bundle branch block (CLBBB) after HF management and a possible benefit of administering sodium-glucose cotransporter-2 inhibitors (SGLT2is) beyond their effects on HF outcomes.
