In this course, we teach you the basic principles underlying the generation of the 12 lead ECG readout. We teach you the basic vector principles relevant to understanding electrocardiography. We explain how the normal depolarization and repolarization events of the cardiac cycle result in a predictable ECG readout and we detail the terminology used to describe the deflections recorded on the readout. We illustrate the crucial geometrical relationship between the frontal leads of the ECG. We teach you how to measure a range of key variables, the PR interval, the qrs duration, the QT interval and how to calculate the heart rate on the ECG. We explain and describe normal ECG T wave polarity.
