WebWhen the electrical system of the heart does not operate as it is supposed to, early repolarization (ERP) can develop. ERP can be seen on an electrocardiogram (EKG). … WebFeb 2, 2024 · Depolarization: An electrical shift that takes place within muscle cells, causing the muscle to reach action potential and ultimately contract. The electrical shift is measurable via the EKG, and allows the clinician to visually predict what the heart is doing and in what pattern. All muscle cells go through depolarization when they contract.
