Highlights:
Students measure an ECG and work out the corresponding moving electric dipole moment of the heart
Abstract:
This resource provides background reading and lecture materials to prepare students to understand the underlying physics behind the electrical signal produced by the beating heart on the body surface, recorded in the form of an electrocardiogram (ECG). Then, in the laboratory, students measure their own ECGs and from their data calculate and display the moving electric dipole moment of the heart that produced that signal. Students should gain a deeper understanding of electric dipoles and how the basic physical mechanism that produces the heart's dipole moment comes from the electrical activity of the heart at the cellular level.
