How the Heart Contracts: Understanding the Electrical Activity and Heart Arrhythmias
In this video, the teacher explains how the heart is able to contract dependably through its natural pacemaker, the SA node, and other specialized cells. The electrocardiogram (ECG) is also discussed as a highly effective method of...
Curated Video
The Pacemaker Potential of the SA Node and the AV Node
In this episode, I talk about how the Pacemaker Potential results in the signal that causes the heart to beat. I show how the greater conductance for Sodium ions in the Pacemaker Cells in the S.A. Node cause the cells to depolarize,...

The Cardiac Muscle Action Potential EXPLAINED
In this video, we explore the biochemical events that take place during the action potential of an individual cardiomyocyte.

The Cardiac Conduction System
In this video, we discuss the components of and functions of the electrical conduction system of the heart.

EKG Patterns Supraventricular Tachycardia
In this playlist, we discuss clinically relevant EKG patterns. This video specifically covers supraventricular tachycardia (and its basic mechanism).
