This spike is called the QRS complex. The bundle of His, bundle branches, and Purkinje fibers are responsible for this.
WebOnce you've determined that a P wave precedes each QRS complex, you must scrutinize the P wave for contour and size. The normal P wave is less than 0.12 seconds in duration, and the largest deflection, whether positive or negative, should not exceed 2.5 mm. An abnormal P wave may indicate atrial enlargement. WebJun 12, 2016 · A normal P wave originates from the Sinoatrial Node , SA node.

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.
