WebNov 1, 2024 · The P-wave (sometimes P-top) represents electrical depolarization in the atria. To find out more about how this electrical activity occurs have a look at the action potential article. In short, depolarization means that an electrical signal is moving through a nerve or heart muscle cell membrane. WebThe P wave represents the wave of depolarization that spreads from the SA node throughout the atria and is usually 0.08 to 0.10 seconds (80-100 ms) in duration.
