Introduction to ECG | The Basics | Einthoven’s Triangle, Limb, Augmented and Precordial Leads

The video tutorial explains Einthoven's triangle and ECG lead placement, covering limb, augmented, and precordial leads. It details the placement and function of each lead type, including their positive and negative electrodes. The tutorial also discusses the heart's depolarization process and how it relates to lead angles, emphasizing the importance of lead two. The precordial leads are described as projecting perpendicularly from the screen, providing a comprehensive understanding of ECG lead systems.

What is Einthoven's triangle and how is it formed?

Describe the three leads formed by Einthoven's triangle.

How can you remember the placement of the leads in Einthoven's triangle?

What are augmented leads and how do they differ from limb leads?

Explain the significance of the positive and negative electrodes in augmented leads.

What is the mean vector of depolarization in the heart and how does it correspond to lead placement?

What are precordial leads and how do they relate to limb and augmented leads?

How do the degrees of the leads relate to the heart's depolarization?

List the degrees associated with lead one, lead two, and lead three.

Why is lead two considered particularly important in understanding heart depolarization?
