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 ...

Sept. 25 (UPI) --Researchers have succeeded in creating a digital twin that for the first time replicates the heart's electrical conduction system, which coordinates heartbeats, a new study says. The ...

Heart rhythm measures in the electrocardiograms of the first pig-to-human heart transplant found unexpected differences in the electrical conduction system of the genetically modified pig heart ...

The heart is a natural pump made of muscle tissue, and, like every muscle, it needs energy to function. The heart’s pumping action is regulated by an electrical conduction system that coordinates the ...

Researchers from UCL (University College London) and the ESRF (The European Synchrotron) have produced the first three-dimensional map of the heart's electrical wiring in Tetralogy of Fallot, one of ...

The γ-aminobutyric acid (GABA)ergic system is the primary inhibitory system in the central nervous system, functioning to reduce neuronal excitability. Recently, Liang et al. discovered that this ...

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 ...

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 ...

For patients with heart failure, a reduced ejection fraction, and an indication for cardiac resynchronization therapy (CRT), using His-Purkinje conduction system pacing (HPCSP) is safe and feasible ...

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

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.
