Death of heart tissue usually due to occlusion of a coronary artery is called:
Choose an answer
1 47% 2 Myocardial infarction
Decreased intrinsic SA node rate
associated with a longer
3 4 ventricular diastole
repolarization time and lower slope
of phase 4
Don't know?

,47% Calculate the ejection fraction of the patient.
HR=70 BPM, EDV=150 ml, ESV=80 ml
by dividing by the body surface area Most physiologic measurements are adjusted to a
(BSA) patient's body size (indexed) by:
(Cardiac Index=CO/BSA)
Digitalis or other inotropic drugs These Starling curves are from a patient in CHF. He
is at point A. and is experiencing symptoms of mild
dyspnea. Which management regimen below
would move him to point 1 on the curve?
a. volume expansion or increased salt intake
b. decompensation: continued deterioration
c. Diuretic: or sodium restricted diet
d. Digitalis: or other Inotropic drug
Preload End diastolic filling or stretching of the ventricle is
termed:
ventricular diastole LV preload occurs entirely during
contracting calf muscle, sympathetic Cardiac filling pressure (CVP) increases with
vasomotor activity, exercise (choose all that are correct):
1-contracting the calf muscle
2-sympathetic vasomotor activity
3-standing in an upright position
4-hemorrhage
5-exercise
, Inotropism The intrinsic ability for the heart to contract with a
particular intensity is termed:
automaticity The intrinsic ability of the heart muscle and
automatic tissue to generate its own depolarization
is termed:
Afterload If all other factors are held constant, increasing_____
will decrease cardiac output.
+ inotropism An increase in the contractile state of the
sarcomere usually caused by a stimulant such as
epinephrine (adrenaline) is termed:
inotropic LV contractility is a measure of the hearts ______
state.
decreased systemic vascular At peak exercise a normal individual's mean blood
resistance pressure may not significantly elevate, even though
CO may increase up to seven times. This regulation
of BP on exercise is due to ____________ vascular
resistance.
Decreased intrinsic SA node rate Trained athletes have a lower resting heart rate
associated with a longer than non-athletes because of:
repolarization time and lower slope
of phase 4
Increased blood pressure The hemodynamic effect of increasing the patient's
peripheral vascular resistance is to: (assume
constant CO)
