LBBB is linked to electrical abnormalities, causing inefficient heart pumping, dilation, and systolic dysfunction. The study found LBBB associated with increased heart failure risk, surpassing other ...
Left bundle branch block (LBBB) is an important electrocardiographic (ECG) finding strongly associated with left ventricular systolic dysfunction (LVSD), a condition linked to poor clinical outcomes.
Cardiac physiologic pacing, also known as cardiac resynchronization therapy, is indicated in patients with heart failure, reduced left ventricular ejection fraction (LVEF) of 50% or less, and either a ...
