Webb4 feb. 2024 · Right bundle branch block produces an RSR’ pattern in V1 and deep slurred S waves in the lateral leads. Left bundle branch block produces a dominant S wave in V1 with broad, notched R waves and absent Q waves in the lateral leads. Hyperkalaemia is associated with a range of abnormalities including peaked T waves; WebbP-waves have speeds of 4 to 7 km/s, and S-waves range in speed from 2 to 5 km/s, both being faster in more rigid material. The P-wave gets progressively farther ahead of the S …

WebbNo, it doesnt. you're confusing P&S waves with Love and Rayleigh waves. Wish people would stop confusing these phenomena. Love and Rayleigh waves are the surface waves that do the damage during a quake; P and S waves can only be measured on instrumentation and DO NOT always coincide with the onset of shaking. city of tillamook https://elmobley.com
