afterdepolarization
Afterdepolarization refers to abnormal electrical activity in cardiac cells that occurs after the repolarization phase of an action potential. It is a phenomenon that can lead to triggered arrhythmias. Afterdepolarizations are broadly categorized into early afterdepolarizations (EADs) and delayed afterdepolarizations (DADs).
Early afterdepolarizations occur during or shortly after repolarization, when the membrane potential is still negative but
Delayed afterdepolarizations occur after the cardiac cell has fully repolarized and returned to its resting membrane
