Anatomy explanation on arrhythmias, Wolff's-Parkinson-White syndrome, heart attack (myocardial infarction) and ventricular fibrillation (visit http://watchlearnlive.heart.org/CVML_Player.php?moduleSelect=arrhyt for ventricular fibrillation animation)

2. INTRODUCTION
Four things that will be discuss :1.Arrhythmias
2.Wolff’s-Parkinson-White
Syndrome (WPW Syndrome)
3.Heart Attack
4.Ventricular Fibrillation

3. ARRHYTHMIAS
Define:
Irregular heart beat
Description:
Problem with the conducting fibers. Can
occur in
normal or tachycardia or bradycardia heart
beat

4. • Abnormal (extra) signals may occur
• Electrical signals may be blocked or
slowed
• Electrical signals travel in new or different
pathways through the heart

5. WPW SYNDROME
Wolff-Parkinson-White Syndrome
Define:
Extra, abnormal electrical pathway in the
heart
that leads to periods of a very fast heart beat
(tachycardia).
Description:
Can causes by:
• Congenital heart disease
• Inherited disease
• Gene mutation

6. Normal pathway
VS
WPW syndrome pathway

7. HEART ATTACK
Define:
When there is a blood clot blocks the flow of
blood through a coronary artery
Description:
Interrupt blood flow that occurs during a heart
attack can damage or destroy a part of the heart
muscle
*also known as myocardial infarction

9. VENTRICULAR FIBRILLATION
Define:
Lower chambers quiver and the heart can't
pump any
blood, causing cardiac arrest
Description:
The heart's lower (pumping) chambers contract
in a
rapid, unsynchronized way. (The ventricles
“flutter”
rather than beat.) The heart pumps little or no
blood

11. CONCLUSION
1. Arrhythmias: irregular heart beat
2. Wolff’s-Parkinson-White Syndrome (WPW
Syndrome): extra abnormal pathway for electrical
impulse
3. Heart Attack: blood clot block in coronary arteries
4. Ventricular Fibrillation:
Ventricular quiver and cannot pump blood or pump
very little amount of blood
