Heart Lab

This blog is to sum up the ECG lab. In this lab we measured our heartbeats. We were able to do this by hooking up electrodes to our arms and then connected by wires the electrical currents were able to be picked up. We measured several people and it was crazy to see how different all of them were. Jodi's was the highest of all of the graphs and I am not exactly sure why this was. Her R wave was definatly had the highest peak a long with the S wave having the highest dip. Then we also measured me and Nicks and ours were much different. Our heartbeats were very straight and did not have such extreme peaks and dips in the QRS complex unlike Jodi's. This could be because we were more relaxed or that it was low because we were in basketball and were in good condition. Whatever the case this blog showed the close up of these wiggly lines called the QRS complex.

At the finale of this lab we also got to play around with blood pressure while using interesting instruments. We used several different types of readers such as the normal velcrow and pump ones that are found in most doctors offices or the newer ones that are put around the wrist and automatically take the reading. From the lab I learned that is typical for women to have a slighty lower blood pressure for whatever reason that may be.
