Assume that there are two different signals going on in the ECG - during depolarisation and repolarisation in the standard ECG. I got an advice that do not use the standard ECG in measuring exactly the electric events during
- stages 0-2
We can get data about the electric activity of neurons in vivo:
where some data about the electric activity of neurons. So a similar technique can probably work with cardiomyocytes.
I estimate that I get about 18% uncertainty by using the standard ECG because of the peak in the stage 1 (Gibbs phenomenon) and those two complete different phases.
How can you measure Na/K channel activation in membrane level?
