The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

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 ...

Multicenter randomized trial (n=200) assigned LBBP versus BiVP for CRT in LBBB with LVEF ≤35%, using time to death or HF hospitalization as primary endpoint. Event rates favored LBBP, reducing death ...

The UltiSynq lead integrates conduction system pacing into ICD systems without requiring an additional ventricular lead or off-label adaptations, a common limitation with previous approaches. By ...
