electrocardiography, the atrial action potential are action potentials that occur in the heart atrium. They are similar to ventricular action potential with the exception...

intercalated discs which allow the action potential to pass from one cell to the next. This means that all atrial cells can contract together, and then...

An action potential occurs when the membrane potential of a specific cell rapidly rises and falls. This depolarization then causes adjacent locations...

pacemaker potential or current which drives rhythmic modulation of firing rate. Some pacemaker action generate rhythms for the heart beat (sino-atrial node)...

cells are less equipped to contract compared to the atrial and ventricular cells. Action potentials pass from one cardiac cell to the next through pores...

Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of...

that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia....

atrium is roughly cube-shaped except for an ear-shaped projection called an atrial appendage, previously known as an auricle. All animals with a closed circulatory...

producing a wave of electrical impulses that stimulates atrial contraction by creating an action potential across myocardium cells. Impulses of the wave are...

atrial cells) into pacemaker cells. This is achieved by making the cells express a gene which creates a pacemaker current. Pacemaker action potential...
