Webb11 mars 2024 · Q waves are inscribed when the initial QRS vector is directed away from the positive electrode. The R wave is the first positive deflection of the QRS complex; its amplitude varies by age, race, and cardiac pathology, and it should increase across the precordium from leads V1 to V5. The negative deflection after the R wave is the S wave. Webb11 aug. 2016 · Primary (P) and secondary (S) waves are two types of waves caused by earthquakes.
