2A Flashcards
What are the two focuses of the cardiac cycle/wigger diagram?
Mechanical and electrical
What is systole?
Contraction & Emptying (have atrial and ventricular) (separate)
What is diastole?
Relaxation and Filling (atrial and ventricular)
What is the max SV?
120ml/beat…holy S!
What is the max HR?
230 BPM holy S!
What is the formula for CO?
CO=HR x SV (Cardiac Output)
What is the quantity of blood pumped by either ventricle per minute?
Cardiac Output
What is the max CO?
20-25L/min HOLY S!
What SHOULD venous return equal?
Cardiac Output (amount of blood returned per minute)
What is ESV? How can I find it?
Amount of blood at the end of systole…EDV (130ml)-SV(70ml)=60ml(End Systolic Volume)
What is the first step of our wiggins where the mitral valve opens?
End of IsoVolumetric Ventricular Relaxation
What are the three phases of ventricular filling?
1.Rapid,Passive Filling 2.Slow Passive filling (diastasis) 3.Atrial Systole
When is the third heart sound produced?
Rapid,passive ventricular filling
What percent of total ventricular volume is happening in our atrial systole”topping off” phase?
10-15%
What is the MOST important phase on the wigger diagram? What ECG corresponds?
IsoVolumetric Contraction (the strongest ventricular contraction!)…QRS
