Steven Poelzing, an associate professor at the Virginia Tech Carilion Research Institute, recently joined a podcast from the American Journal of Physiology highlighting recent research results in his field of expertise. Along with Igor Efimov, an editor from the journal, Poelzing helped explain a study’s significance in the area of cardiac electrophysiology. The experiment showed that by prolonging action-potential duration, bradycardia might destabilize calcium and cause arrhythmia. Poelzing contributed by discussing how intracellular calcium can affect the electrical signals that propagate through the heart, and through calcium-voltage coupling, can become the original source of arrhythmia.
