Splet04. feb. 2024 · Example ECG showing both narrow and broad complexes. Sinus rhythm with frequent ventricular ectopic beats (VEBs) in a pattern of ventricular bigeminy. The narrow beats are sinus in origin, the broad complexes are ventricular. ... Left bundle branch block produces a dominant S wave in V1 with broad, notched R waves and absent Q waves in … S waves are transverse waves, meaning that the direction of particle movement of a S wave is perpendicular to the direction of wave propagation, and the main restoring force comes from shear stress. Therefore, S waves cannot propagate in liquids with zero (or very low) viscosity; however, they may propagate in … Prikaži več In seismology and other areas involving elastic waves, S waves, secondary waves, or shear waves (sometimes called elastic S waves) are a type of elastic wave and are one of the two main types of elastic body waves, … Prikaži več • Earthquake Early Warning (Japan) • Lamb waves • Longitudinal wave Prikaži več In 1830, the mathematician Siméon Denis Poisson presented to the French Academy of Sciences an essay ("memoir") with a theory of the … Prikaži več Isotropic medium For the purpose of this explanation, a solid medium is considered isotropic if its strain (deformation) in … Prikaži več • Shearer, Peter (1999).
