The SARS-CoV-2 virus can infect specialized pacemaker cells that maintain the heart's rhythmic beat, setting off a self-destruction process within the cells, according to a preclinical study. The ...
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 ...
An increasing number of reports suggest that cardiac arrhythmias are frequent clinical features of COVID-19. A New York-based team of researchers explored the impact of SARS-CoV-2 infection on the ...
The sinoatrial (SA) node is the natural pacemaker of the heart. It generates electrical impulses that cause the heart’s chambers to contract, setting the heart rate. The SA node typically generates 60 ...
A new study shows that the sinoatrial node (SAN) -- a small but powerful structure in the human heart that serves as its natural pacemaker and initiates every normal heartbeat -- runs on different ...
The autonomic nervous system innervates all body organs, including the cardiovascular system. Smooth muscle in arteries, arterioles, and veins and pericytes in capillaries receive autonomic ...
Tachycardia describes when the heart beats faster than normal. Sinus rhythm with tachycardia occurs when the sinus node fires electrical impulses abnormally quickly. Inappropriate sinus tachycardia ...
