WebIt is normal not to see a q wave in V1-V3. the r wave is the first positive/upward deflection following the p wave so even though we are used to seeing tall peaked r waves, following this definition that is the r wave. the S wave is the first negative deflection following the r wave, thus that large negative wave is the S wave. WebWhen the pH of the solution equals pK a, the concentrations of HA and A (-) must be equal (log 1 = 0). (25.3.1) p K a = p H + log 10 [ H A] A −] The titration curve for alanine in Figure 25.3. 2 demonstrates this relationship. At a pH lower than 2, both the carboxylate and amine functions are protonated, so the alanine molecule has a net ...

WebFeb 4, 2024 · QRS Width. Normal QRS width is 70-100 ms (a duration of 110 ms is sometimes observed in healthy subjects). The QRS width is useful in determining the origin of each QRS complex (e.g. sinus, atrial, junctional or ventricular). Narrow complexes (QRS < 100 ms) are supraventricular in origin. Broad complexes (QRS > 100 ms) may be either …
