Researchers from UCL (University College London) and the ESRF (The European Synchrotron) have produced the first ...

Scientists studying genetic data from nearly 50,000 people have uncovered several DNA sequence variations associated with the electrical impulses that make the heart beat. The findings may pave the ...

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 ...

Researchers have produced the most detailed and comprehensive human Heart Cell Atlas to date, including the specialized tissue of the cardiac conduction system -- where the heartbeat originates. In a ...

ECG aberrancy means the heartbeat does not follow the usual conduction system of the heart. Atrial fibrillation with ECG aberrancy means people have an irregular heart rhythm with abnormal conduction.

NEW ORLEANS -- Among patients with heart failure, conduction system pacing-guided cardiac resynchronization therapy was associated with improvements in left ventricular ejection fraction (LVEF) ...

A pacemaker may be useful for atrial fibrillation (AFib) involving a slow heart rate or other heart conduction disorders. However, doctors may recommend lifestyle changes to manage AFib before a ...

Elevated resting heart rate is associated with greater risk of cardiovascular disease and mortality. In a 2-stage meta-analysis of genome-wide association studies in up to 181,171 individuals, we ...

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 ...
