This activity will build upon the concepts taught in the lesson The Strongest Pump of All. The activity will pull together the concepts of bioelectricity, electrical circuits, and biology. It will allow the students the opportunity to use deductive and analytical thinking skills in connection with an engineering education. The students will be able to interact with a rudimentary Electrocardiograph circuit and examine the simplicity of the device. The students will be to visualize their own cardiac signal and test the device themselves. The second part of the activity will be a series of worksheets where the students examine different EKG printouts and look for irregularities. The irregularities will be connected to disease detection using EKG.

In this lesson the students will learn how the heart functions. Students will be introduced to the concept of action potential generation. The lesson will explain how action potential generation causes the electrical current that causes muscle contraction in the heart. Students will be introduced to the basic electrical signal generated by the heart; P, QRS, and T waves. The lesson will approach the heart from an engineering standpoint and encourage students to design ways to improve heart function. Students will also learn the basic steps of the engineering design process.
