Term

25/8

Right ventricle

Definition
What is pulmonary arterial pressure supposed to be? It is the same as _____.
Term

2,

25/8,

5,

120/8

Definition

What is the pressure of the right atrium?  right ventricle? left atrium? left ventricle.

NORMALLY.

Term

Atrial depolarization

Ventricular depolarization

Ventricular repolarization

Definition

Define p wave. 

Define QRS complex. 

Define T wave.

Term
During mitral valve stenosis and during tachycardia.
Definition
At what 2 times (problems) is atrial contraction very important?
Term
Ventricular hypertrophy. It is the sound of pushing blood into the ventricle. Mid to late diastolic.
Definition
When would you hear an S4.
Term
It is the sound of rapid ventricular filling. In the beginning of diastole.
Definition
When would you hear S3.
Term
Called a fixed split. S2 is split on inspiration and exhalation.
Definition
Septal defect will push blood to the right side of the heart and do what to S2? What is this called?
Term

Wide split.

It is greater during inhalation bc VR is augmented. 

 

The pulmonary artery is narrowed so it takes longer for blood to get pushed into it.

Definition
Pulmonic stenosis produces what kind of split.
Term
paradoxical splitting. the aortic valve is narrowed so it takes longer for blood to be pumed out. When you inhale, the VR is augmented and the pulmonic valve closes RIGHT after the aortic. During exhalation the aortic does not change but the pulmonic valve beats the aortic valve closed.
Definition
Aortic stenosis produces what kinds of S2.
Term
SV * HR
Definition

What is the formula for CO?

 when you have SV

Term
EJ= SV/ EDV
Definition
what is the formula for Ejection fraction?
Term
SV= EDV-ESV
Definition
what is the formula for SV
