Key result
Septal flash magnitude during RV pacing correlates with LV dysfunction and adverse remodeling.
Why the study?
Is the magnitude of a septal flash related to LV dysfunction and adverse remodelling in patients receiving conventional RV pacing?
Is the magnitude of a septal flash related to LV dysfunction and adverse remodelling in patients receiving conventional RV pacing?
The magnitude of a septal flash in patients with conventional RV pacing is related to LV dysfunction and adverse remodeling, suggesting it may serve as a predictor for these complications.
Septal flash magnitude may flag LV dysfunction risk in RV-paced patients; hypothesis-generating and requires prospective validation before clinical use.
A SF was present in a majority of patients receiving conventional RV pacing and its magnitude was related to LV dysfunction and adverse remodelling. Given the similarities observed in LBBB and pacemaker-induced dyssynchrony, SF magnitude might be a predictor for the development of LV dysfunction and adverse remodelling in patients receiving conventional RV pacing.
