WebFeb 25, 2024 · Response to ECG Challenge. The ECG showed sinus rhythm with 2 alternating different P-wave morphologies ( Figure 2 ): the narrow P-wave duration was 100 ms, the wide P-wave duration was 170 ms, and the peak appeared to have bifid morphology. The PR intervals also exhibited 2 types: the short interval was 160 ms, and the long interval was …

P wave - Wikipedia

Primary and secondary waves are body waves that travel within the Earth. The motion and behavior of both P and S waves in the Earth are monitored to probe the interior structure of the Earth. Discontinuities in velocity as a function of depth are indicative of changes in phase or composition. Differences in arrival times of waves originating in a seismic event like an earthquake as a result of … Web2. Seismic P-Wave Behavior P-waves traveling through rock are analogous to sound waves traveling through air. The speed a P-wave propagates through a medium depends on the physical properties (i.e. rigidity, density, saturation) and degree of homogeneity of the rock. Spherical wave fronts emanate from a source, as well as ray paths. bts cypher pt. 1

"WebSeismic waves are caused by the sudden movement of materials within the Earth, such as slip along a fault during an earthquake. Volcanic eruptions, explosions, landslides, avalanches, and even rushing rivers can also cause seismic waves. Seismic waves travel through and around the Earth and can be recorded with seismometers.

WebIn order to distinguish between the two potential rhythms when an ECG reveals 2:1 AV nodal block, a couple different maneuvers can be employed: Carotid sinus massage or adenosine: This slows the sinus rate allowing the AV node more time to recover, thus reducing the block from 2:1 to 3:2 and unmasking any progressing prolonging PR intervals WebRayleigh waves involve interaction between P and 5 waves at a free surface; thus we must further explore the nature of body-wave reflection coefficients at the free surface. We consider the two cases shown in Figure 4.1, for incident P and incident SV plane waves impinging on a free surface. A free surface requires the tractions to vanish at x 3 = 0; σ 33 …

These waves travel in the speed range of 1.5-13 km/s. These waves are almost 1.7 times slower than P waves. These waves travel in a linear direction. These waves travel in a transversal direction. These waves can travel through solid, liquid, and gas.

WebApr 5, 2024 · Although it is an uncommon finding, a few case reports on patients having undergone heart transplantation have described that the residual atrial tissue from the recipient’s heart could produce another P-wave from the donor’s heart. 1, 2 These dual P-waves are also known as a complete pseudo-atrioventricular block, and the physician … WebThe P-wave is always positive in lead II during sinus rhythm. This is rather easy to understand because lead II is angled alongside the P-wave vector, and the exploring …
