EKG Lab

In the class, we did a lab to look at the different waves in our heart beats, including the P, Q, R, and S waves. By doing this we used an EKG sensor. First, we put a positive EKG sensor on our left forearm. Then, a negative on the right forearm. We also put a ground clip to the right wrist. After we were all hooked up the computer showed us our waves. It was cool to see mine compared to others in the classroom because all of ours were different. My group also noticed that boys had higher waves then girls. It was really neat to see!
