Practical (laboratory) lesson No 8. BIOPHYSICAL BASIS OF ELECTROGRAPHY

Students should study the material on the topic and be able to answer the following questions:

1. Resting potential (RP). RP formation mechanism. Goldman-Hodgkin-Katz equation.
2. Action potential (AP). The mechanism of action potential formation on the membranes of nerve and muscle cells.
3. Electric dipole. Dipole electric field.
4. Current dipole. Electric field of a current dipole in an unlimited conducting medium.
5. Concept of a dipole equivalent generator of the heart, brain and muscles.
6. Einthoven's model. Genesis of electrocardiograms in three standard leads within this model.

Guidelines

1. Learn the lecture presentation material
2. Write the protocol in the workbook, as described in the file "Biophysical fundamentals of ECG."
In a concise protocol theory, reflect the answers to the questions in the session topic.
3. Watch an instructional video
4. Select an electrocardiogram from the file with individual tasks. The variant number is determined by the number to the left of the forward slash of the grade book number. For example 37/19. Option 7. Perform calculations.
5. Complete the lab report and email the instructor a photo of the report.
