On the ventricular PV curve, what point is "End systolic volume"?
at the end of curve III
what is normal left atrial pressure?
1-5 mmHg
Oxygen consumption is nearly proportional to _________
the Tension that is created times the duration of the contraction (tension-time index)
Main energy source of heart?
fatty acids
When systolic pressure in high, tension is high and more _____ is consumed.
oxygen
When the ventricle is dilated more oxygen is also consumed because the tension during contraction is related to ___________
the diameter of the ventricle time the pressure
Minute work output = ?
stroke work output times the heart rate.
The maximal efficiency of the normal heart is _______
20 to 25% with this value falling during heart failure.
In EKG: the atrial wave
P
In EKG: the ventricular depolarization
QRS wave
In EKG: the ventricular repolarization wave?
T wave
When is the incisura dip in the aortic pressure curve?
aortic vale closure
"a" of the atrial pressure curve (a,c,v)
atrial contraction
"c" peak of atrial pressure curve
caused by ventricle contraction interuppted by aortic valve opening
"v" peak in atrial pressure curve
slow rise of "v" curve is interupted by A-V valve opening
