Basics of ECG VECTOR
There are three basic "laws" of Electrocardiography. These "laws" have to do with the direction of flow of electrical conduction in the heart or what we term as vector.
1. Movement of the electrical impulse towards the positive electrode will result in a positive deflection on the ECG.
2. Movement of the electrical impulse toward the negative electrode will result in a negative deflection on the ECG.
