BIOC34H3 Chapter Notes -Atropine, Vasodilation, Calcium Channel Blocker
Document Summary
Perform the experiments in physioex lab 6 (cardiovascular physiology). Provide the results requested, and answer the questions, for each of the following activities. Note: the activity names and numbers listed below correspond to those in physioex version 9. 0. If you are using an older version of physioex the exact activity names and numbers may not match. In this case, identify which activities in the older versions correspond to the ones listed below and place the appropriate data in the corresponding section. Activity 1: investigating the refractory period of cardiac muscle. Results: briefly describe what happened when you applied the electrical stimuli to the heart. (2 marks) Applying electrical stimulation to the heart resulted in an extrasystole. During the extrasystole, the ventricle contracted during relaxation and a bimodal peak (doublet) appeared on the oscilloscope. Following this, there was a brief halt to allow heart beat to return to normal.
