WebNational Center for Biotechnology Information WebSudden cardiac arrest is among the leading causes of death in the United States. In fact, more than 350,000 people will suffer a cardiac arrest this year. Currently, the only way to restore a regular heart rhythm during cardiac arrest is to use an AED. Of course, you can – and should – request the assistance of trained medical professionals.

Calcium and cardiac arrhythmias: DADs, EADs, and alternans

WebEarly afterdepolarizations (EADs) develop during repolarization of the action potential (phase 3) and are most common during slow heart rates or after long pauses. EADs can … 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.
