Основи аналізу ЕКГ. Урок 1

Basics of ECG analysis. Lesson 1. I know that there are already many videos on ECG, but after them you still won't be able to decipher the ECG or it will be very difficult to remember. The purpose of this video course is to present the information in such a way that these are the last videos on ECG that you watch, because you will be able to easily decipher the main pathologies on the ECG. While myocardial cells are not stimulated, they are at rest, which means that the cells must have a resting membrane potential (MPP). MPP of myocardial cells = - 90 mV. When stimulated, cations (positively charged particles) begin to enter the cell and the MPP reaches a critical level ( - 70 mV), at which potential-dependent sodium channels open and sodium enters the cell in an avalanche. This leads to complete neutralization of the electronegativity of the cell and it becomes electropositive. That is, we say that the cell has become depolarized, and this phenomenon is called depolarization. More information in this video.
