WebThese aberrant depolarizations are often the result of myocardial remodeling and frequently originate within the muscular sleeves that extend into the pulmonary veins from the atria. Causes include hypertension, valvular and ischemic heart disease, and genetics (e.g., mutation of 10q22 – q24 on chromosome 10). EADs most commonly originate in mid- myocardial cells and Purkinje fibers, but can develop in other cardiac cells that carry an action potential. Phase 2 may be interrupted due to augmented opening of calcium channels, while phase 3 interruptions are due to the opening of sodium channels. See more Afterdepolarizations are abnormal depolarizations of cardiac myocytes that interrupt phase 2, phase 3, or phase 4 of the cardiac action potential in the electrical conduction system of the heart. Afterdepolarizations … See more Early afterdepolarizations (EADs) occur with abnormal depolarization during phase 2 or phase 3, and are caused by an increase in the … See more Delayed afterdepolarizations (DADs) begin during phase 4, after repolarization is completed but before another action potential would normally occur via the normal conduction … See more
