WebJul 9, 2024 · First, make sure that there are actually P waves on the EKG strip because there are certain dysrthythmias where P waves are missing. Once you’ve determined that a strip includes P waves, you’ll want to make sure the P waves are occurring regularly and have a consistent appearance across the strip. WebA P wave ( primary wave or pressure wave) is one of the two main types of elastic body waves, called seismic waves in seismology. P waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph.
