The Long Plateau Phase Due to the Influx of Calcium Ions – Action Potential in Cardiac Cells
The action potential in cardiac cells is a fascinating process that underpins the heart’s rhythmic contractions, with a distinctive long plateau phase driven by calcium ion influx. This diagram highlights the long plateau phase and extended refractory period, illustrating how these features ensure the heart completes its contraction cycle effectively. Exploring this image provides a deeper understanding of the electrophysiological mechanisms that sustain cardiac function.
