Normally, the QRS complex is 0.06 to 0.11 sec (60 to 110 msec) wide. A QRS complex wider than 0.11 sec indicates either a bundle branch block or a QRS complex of … Web26 de jun. de 2024 · S-waves travel faster than P-waves. Why P waves Cannot be recorded in the outer core? This indicates that P-waves slow down in the outer core, suggesting that this layer has a significantly different composition from the mantle and may actually be liquid. This bending in the outer core creates a P-wave shadow zone where … greenwood lake ny restaurants on the lake
