Students will review:
In this chapter, you'll learn the answers to questions including:
- What are the parts of the heart, and how does blood flow through its chambers?
- What happens during each beat of the heart?
- How does the intrinsic conduction system work?
- How can an electrocardiogram (ECG) detect heart arrhythmias and problems?
- What are some of the major cardiac conditions and diseases?
- What are some of the major congenital defects of the heart?
1. Anatomy of the Heart: Blood Flow and Parts
In this lesson, you will take a look inside the heart and identify the chambers and one-way valves that make up this vital organ. You will also follow along as we trace the flow of blood through the heart chambers.
2. The Cardiac Cycle: Phases, Explanation & Terms
In this lesson, you will learn what happens during each heartbeat, or cardiac cycle. You will also learn that the heartbeat involves periods of relaxation and contraction, known as diastole and systole, respectively.
3. Heartbeat and Heart Contraction Coordination
In this lesson you will learn about your heart's very own regulatory system, the intrinsic conduction system, and how it sets the pace for a normal, healthy heartbeat. You will discover that your heart moves to its own beat thanks to the natural pacemaker of the heart called the SA node.
4. Electrocardiogram (ECG): Definition & Wave Types
Do you know how problems in the heart are detected? In this lesson, you will learn how to read an electrocardiogram (ECG) and discover what is happening in the heart during the P, QRS, and T waves.
5. 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.
6. Types of Heart Conditions and Diseases
Your heart muscle receives a rich blood supply from the coronary arteries. If the coronary arteries become blocked, it can result in coronary heart disease, angina, heart attack or congestive heart failure. Learn how these conditions get started.
7. 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.
8. 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.
9. Patent Ductus Arteriosus: Causes, Signs, and Treatment
A patent ductus arteriosus can be a life-threatening problem that occurs as a result of a failure of closure of an important fetal structure. We'll talk about what fails to close and how it affect the newborn.
