Relate the changes in the ECG to changes in the cardiac cycle--what is happening in terms of valves and chambers? PR is shortened; this means that valves and chambers are closing more quickly 12 Question #12: Hypothesize what is meant by an AV Block. when the electrical signal traveling from the atria, or the upper chambers of the heart, to ventricles, or the lower chambers of the heart, is impaired 13 Question #13: Based on the ECG tracing, hypothesize the altered path of electrical activity that happens in a second-degree AV block. there are less consistent qrs intervals and the rhythm is erratic 14 Question #14: Do you observe a change in blood pressure with a second-degree AV block? Why or why not? Explain your answer using the cardiac cycle and blood pressure formula. you will have a lower blood pressure because the cardiac output is lower 15 Question #15: What is the difference between the second-degree and third-degree AV block on the ECG recording? What do you think is happening to the path of electrical activity? in second degree some electrical impulses are still happening, in third degree none of the electrical

4/12/2020 Results 3/3 impulses from the atria are reaching the ventricles 16 Question #16: Do you observe a change in blood pressure with a third-degree AV block? Why or why not? Explain your answer using the cardiac cycle and blood pressure formula. blood pressure will be very low and the patient will have low cardiac output
