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 ...

New research highlights postnatal regeneration limits and pathological remodeling of the cardiac conduction system after myocardial infarction, uncovering mechanisms behind clinical arrhythmogenesis ...

A recent Nature study uses a combination of single-cell ribonucleic acid (scRNA)-sequencing and high-resolution multiplexed error-robust fluorescence in situ hybridization (MERFISH) to better ...
