P wave - Wikipedia

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. P waves may be transmitted through gases, liquids, or solids. Web476 Likes, 113 Comments - Joel Greene (@realjoelgreene) on Instagram: "NOTES FROM THE SUMMIT: I ascended yesterday. Level 57.

WebWhat does an enlarged P wave mean? If the p-wave is enlarged, the atria are enlarged. If the P wave is inverted, it is most likely an ectopic atrial rhythm not originating from the sinus node. Altered P wave morphology is seen in left or right atrial enlargement. The PTa segment can be used to diagnose pericarditis or atrial infarction.
