1. Arrhythmia of the Heart: Terms, Definition & ECG Detection
An electrocardiogram, or ECG, can be used to detect irregular heartbeats or arrhythmias. In this lesson, you will learn about arrhythmias detected by ECG, including bradycardia, tachycardia, fibrillation, and heart block.
2. What Is Dysrhythmia? - Definition, Symptoms & Treatment
What is a dysrhythmia vs. an arrhythmia? What are the signs and symptoms of cardiac dysrhythmias? How can we treat the various types? This lesson answers all of these questions.
3. Congenital vs. Acquired Heart Defects
Not all heart disease is the same. Some people are born with defects, while others develop diseases later in life. In this lesson we'll look at both types of heart disease, called congenital and acquired heart diseases.
4. Septal Defects of the Heart: Definition, Conditions, and Symptoms
We will mainly take a look at something known as an atrial septal defect and a ventricular septal defect, why they may occur, where they occur, and what they result in, in terms of cardiopulmonary physiology.
5. Tetralogy of Fallot: Definition, Causes and Treatment
This lesson will go over a congenital problem known as Tetralogy of Fallot, the four major components that are involved, and how they act together to cause quite a few problems.
6. Inflammatory Disorders of the Heart
This lesson will discuss inflammatory disorders of the heart, including pericarditis and endocarditis, as well as what they may cause and what significant things may occur during testing.
7. Valvular Dysfunctions: Types, Signs & Treatment Options
This lesson will quickly go over four heart valves, their location, what can go wrong with them, and then two detailed examples of how their dysfunction affects the body.
