How to Read an Electrocardiogram (ECG/EKG)

In this episode, Leslie Samuel explains how to read an electrocardiogram (ECG or EKG). The video covers the basics of ECG, its purpose, and how it records the heart's electrical activity. Leslie discusses the components of an ECG, including the P wave, QRS complex, and T wave, and explains their significance in heart function. The video also touches on the U wave and its potential implications. Viewers are encouraged to visit interactive-biology.com for more resources.

What does the T wave indicate in the context of heart activity?

Why are the signals from the ventricles larger than those from the atria in an ECG?

What is the U wave and when might it be observed in an ECG?
