 This triggers contraction in the atria

• SA node
• AV node
• QT node
• AV Bundles

 This triggers contraction in the ventricle

• SA node

What is going on in the heart during the P wave

• SA node triggers depolarization in atria
• AV node triggers depolarization in ventricle, the main pumpung action
• Delay caused by the SA node
• Repolarization of the ventricle 

What is going on in the heart during the R-wave or QRS complex

• SA node triggers depolarization in atria
• AV node triggers depolarization in ventricle, the main pumpung action
• Delay caused by the SA node
• Repolarization of the ventricle 

What is going on in the heart during the T-wave

• SA node triggers depolarization in atria
• AV node triggers depolarization in ventricle, the main pumpung action
• Delay caused by the SA node
• Repolarization of the ventricle

• Sickle cell anemia

Abnormal sound that consists of flow noise that is heard before, between or after the lubb-dupp o rmask sound entirely

• Heart Murmur

• Valvular insufficiency or incompetency

• Valvular stenosis

An electrocardiogram measures what?

• The amount of pressure exerted on blood vessels.
• The electrical activity of the heart.
• How many times the heart contracts over time.
• The body's temperature caused by friction of blood in vessel.

Which contract in unison??

• Top chambers, then bottom chambers.
• Right Chambers, then the Left Chambers
• All four chambers beat in unison.
