BIOC34H3 Lecture Notes - Sotalol, Atrioventricular Node, Pacemaker Potential
Document Summary
Write a brief (no more than 100 words) introduction that describes the goal of the experiments performed in this lab. (2 marks) Heart rate is the number of heart beats per minute. The heart rate is based on the number of contractions of the ventricles in a certain period of time. Throughout this experiment, the frog heart will be put under various circumstances in order to see their effects on the heart rate. These circumstances include: electrical stimulations at different locations of one wave, constant electrical stimulation for a period of time, and the effects of various drugs, hormones and as well as temperature. The heart rate is expected to change accordingly in each situation due to underlying physiological mechanisms. Write a brief (no more than 300 words) methods section that describes the experiments performed in this lab. Describe the experimental preparation and the various manipulations that were performed.
