Lead One Ratio in Left Bundle Branch Block Predicts Poor Cardiac Resynchronization Therapy Response

BACKGROUND: A low electrocardiogram (ECG) Lead One Ratio (LOR) of the maximum positive/negative QRS amplitudes is associated with lower left ventricular ejection fraction (LVEF) and worse outcomes in left bundle branch block (LBBB); however, the impact of LOR on CRT outcomes is unknown. We compared...
