Webb17 jan. 2024 · The P wave is the first wave on the ECG because the action potential for the heart is generated in the sinoatrial (SA) node, located on the atria, which sends action potentials directly through Bachmann’s bundle to depolarize the atrial muscle cells. … Webb1 nov. 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 …
