Unlock the mysteries of the human heart with this comprehensive and easy-to-understand tutorial on EKG interpretation! We'll break down the basics of electrocardiogram analysis and help you master reading EKGs in no time. Whether you're...

In this video, we discuss the following:<br/>
[1] the main three parts<br/> to an EKG.
[2] the electrical & mechanical events they each represent.

In this video, we discuss how the electrical conduction system generates a pacemaker potential by viewing the action potential diagram.

Action Potential Physiology (Part 2)

Making Biology Fun. In this video, I go through the P wave, QRS complex, T and U waves of the Electrocardiagram and go into the details of what each of them represents. Enjoy!

After Depolarization and Repolarization comes Hyperpolarization, where the membrane potential falls beneath the Resting Membrane Potential. Watch the video to learn more!

Depolarization, repolarization, hyperpolarization - It's all here. Watch this for a review of the action potential.

In this episode, I show how the Action potential is generated in cardiac muscle cells and how this results in Contraction of the Heart. When the action potential happens, calcium ions are released from the Sarcoplasmic reticulum, causing...

What does it take for an action potential to take place? What are depolarization, repolarization, and hyperpolarization? How are voltage-gated ion channels involved? In this video, you will get answers to all these questions.

The second phase of the Action Potential is Repolarization. Voltage-gated Potassium channels open and Potassium leaves the cell making the membrane potential more negative.

Have you ever wondered what commotio cordis is or what causes it? In this video, we dissect the physiological mechanism of commotio cordis.
