Cardiac Flashcards
1
Q
Reducing afterload will:
A
- Increase stroke volume
- Decrease myocardial oxygen requirement
- Decrease ventricular wall tension
- Decrease end diastolic volume
2
Q
What is the effect of tachycardia on coronary blood flow in patients with coronary artery disease?
A
Tachycardia shortens the diastolic phase with resultant DECREASE on the flow of blood in the coronary arteries
3
Q
Following the induction of general anesthesia in a patient with coronary artery disease, the blood pressure falls from 160/90 to 70/40. What is the most likely explanation for the hypotension?
A
Decreased systemic resistance
Negative inotropic effect of anesthetics
