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.

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 ...

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 ...

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 ...

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 ...

In a new study, published today (12 July) in Nature, researchers have produced the most detailed and comprehensive human Heart Cell Atlas to date, including the specialized tissue of the cardiac ...

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

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 ...

Intensive blood pressure control has been suggested to reduce the risk of adverse cardiovascular events. However, the effect of intensive blood pressure control on cardiac conduction system disease ...

Depending on the type of irregular heartbeat (arrhythmia), medication can help slow or regulate a person’s heartbeat. Doctors will assess symptoms to decide the best medication. Medications for ...
