Document Summary
This practical wil1 contain 38 questions worth 2pts = 76pts. Please review the background information in the beginning of each biopac lab as well as lecture notes and any lecture images. Please bring standard calculator and pencil to the exam!! Please practice analyzing the graphs using the practice graphs on line. Memorize relevant formulas! they will not be given!!!! (except for predicted vital capacity formula if needed) Know how to calculate amplitude of waves on ecg trace: height of the wave (ex: r wave, 1. 08 mv, make sure to write millivolts, each box is . 1 mv. Know how to calculate and plot mean qrs and determine mean electrical magnitude, and mean electrical axis: calculations: calculate net qrs for lead i and lead iii. Calculate amplitude for q, r, and s and add them together for each lead. Ex: lead i: q (-. 03 mv), r (+ 0. 48 mv), s (-. 23 mv) = +. 22 mv.
