What Is the Heart Conduction System? The heart conduction system is made up of cells, nodes, and signals that help your heart to beat. In fact, the cardiac conduction system is responsible for our ...

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 ...

Ten months after transplanting the first genetically-modified pig heart into a human patient, researchers continue to report on new findings from the landmark transplant. Their latest study ...

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 ...

One possible treatment option for cardiac arrhythmias are approaches that enhance electrical excitability and action potential conduction in the heart. One way this could be done is by stably ...

New research explains how low levels of the electrolyte sodium in the blood can disrupt the timing of the heartbeat in patients taking widely used rhythm-control medications such as flecainide, which ...

Ten months after transplanting the first genetically-modified pig heart into a human patient, University of Maryland School of Medicine (UMSOM) researchers continue to report on new findings from the ...
