Research by Boston Children's validates an innovative approach to mapping the heart's invisible conduction tissue during surgery. Research data from separate studies show that using electrophysiology ...

Heart conduction disorders can often lead to serious or fatal complications including complete heart block or heart failure. Left ventricular conduction disease occurs when there is an electrical ...

Western-blot analysis demonstrated reduced levels of Tfam protein in the heart of mutant embryonic day (E) 18.5 embryos in comparison with littermate controls, whereas the levels of the mtDNA-encoded ...

In patients undergoing transcatheter aortic valve replacement (TAVR), high‑grade atrioventricular blocks occurring during and after the procedure had distinct mechanisms and predictors. Both ...

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

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 ...

Second-degree heart block is a potentially serious but treatable condition affecting the heart’s electrical system. Treatment may require a pacemaker to stabilize the heart’s rhythm. Electrical ...
