Webb20 maj 2024 · As the P-waves move or propagate, they generate vibration in the body of the rocks through which they pass, the P-waves vibrate parallel to the direction of the wave. This vibration exerts pressure on the material in the direction of the propagation, as an outcome, it creates density differences in the material leading to stretching and …

Types of Earthquake Waves: P Waves, S Waves, L Waves Explained!

WebbEarthquake waves under Earth’s surface have both longitudinal and transverse components as well. The longitudinal waves in an earthquake are called pressure or P-waves, and the transverse waves are called shear or S-waves. These components have important individual characteristics; for example, they propagate at different speeds. fnaf multiplayer 2 download

The action potentials that initiate myocardiocyte depolarization may come from the AV node, from regular cardiomyocytes when certain electrolytes are out of balance, or from ectopic pacemaker cells. An inverted P wave means it is upside down. greenstone farm credit loan ratesWebbAn interval in an ECG is a duration of time that includes one segment and one or more waves. The PR (or PQ) interval starts at the start of the P wave and ends at the start of the QRS. It denotes the conduction of the impulse from the upper part of the atrium to the ventricle. The QRS interval covers the QRS complex from beginning to end. greenstone farm credit ionia

"Webb15 mars 2024 · Remember the P wave on an EKG represents atrial depolarization and the QRS complex represents ventricular depolarization. Therefore, the PR interval represents the time it takes for the electrical impulse to travel from the atria (P wave - atrial depolarization) to the ventricles (QRS complex - ventricular depolarization).
