Journal ArticleDOI

Fixation beats: A novel marker for reaching the left bundle branch area during deep septal lead implantation.

TL;DR: In this article, the ectopic beats with qR/rsRʹ morphology in lead V1 (fixation beats) during lead fixation were investigated to predict whether the desired intraseptal lead depth had been reached, whereas the lack of fixation beats would indicate a too shallow position and the need for more lead rotations.
Journal ArticleDOI

Cardiac resynchronization therapy-induced acute shortening of QRS duration predicts long-term mortality only in patients with left bundle branch block

TL;DR: There was a strong relationship between mortality risk and shortening/widening of the QRS, albeit only in the LBBB group, and patients with non-LBBB morphologies had unfavourable prognosis similar to that in L BBB patients without QRS narrowing.
Journal ArticleDOI

Mortality and morbidity in cardiac resynchronization patients: impact of lead position, paced left ventricular QRS morphology and other characteristics on long-term outcome.

TL;DR: Electrocardiographic and fluoroscopic descriptors of the LV lead position were found to be predictors of mortality/morbidity (as were functional class, heart failure aetiology, hyponatremia, and chronic atrial fibrillation) and the antero-apical pattern of LV QRS complexes and apical or paraseptal LV lead positions should be avoided.
