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 ...

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 ...

When patients with congenital heart issues have an operation, surgeons have to proceed with an "eye of faith" as they work around conduction tissue—a network of cells and electrical signals that ...

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 ...

Vienna, 30 March 2025– The European Society of Cardiology (ESC) has released a groundbreaking consensus statement on conduction system pacing (CSP), marking a significant milestone in the evolution of ...

During a severe heart attack many heart muscle cells die and are replaced by scar tissue to stabilize the heart wall. Connective tissue cells, known as fibroblasts (FB), are the dominant cell type in ...

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.

As an excitatory transmitter system, the glutamatergic transmitter system controls excitability and conductivity of neurons. Since both cardiomyocytes and neurons are excitable cells, we hypothesized ...
