Flashcards in Cardiovascular Jeoparady 4b Deck (19):
1

What type of HF leads to pulmonary edema

Left Heart Failure

2

What can we determine from a chest x-ray?

Size and structure of the heart

3

How do we get blood to the working muscles during exercise if we have high levels of circulating norepinephrine?

blood flow to the working organs is primarily controlled by local metabolic factors
(Although the overall effect on the vasculature is vasoconstriction)

4

Why does your heart rate increase when you think about starting to exercise?

Due to the anticipatory response (sympathetic activity)

5

During exercise, what mechanisms are helping increase venous return?

1) Venous Constriction
2) skeletal muscle pump
3)respiratory pump

6

When do we need to control BP, what mechanism is fastest?

Baroreceptors- sense changes and make adjustments in seconds

7

Insulin resistance contributes to increased peripheral resistance
T/F

True, along with inflammation and endothelial dysfunction

8

For what 2 diseases would you put somebody on a sodium restricted diet?

Hypertension and HF

9

Increased blood flow in skeletal muscle with exercise is due to the active hyperemia or reactive hyperemia?

both,

10

SV increases proportionally with increasing exercise intensity.
T/F

True and False, SV can only increase to a percent (40-60%) of maximal capacity, after which it plateaus

11

Following training, what happens to a person's resting CO?

It remains about the same as before training; this is because as SV increases, HR decreases

12

What type of exercise increases systemic vascular resistance?

Static Exercise

13

What does "White Coat Hypertension" mean?

Doctors (or other medical offices) make you nervous, so when you go, your BP increases

14

What 2 factors effect CO?

HR and SV

15

What's the final option for a person with severe HF?

Heart Transplant or Artificial Heart

16

Myocardial Ischemia will ALWAYS show up on an ECG?

False. often at rest, the ECG will look normal and there needs to be a "stressor" before we see changes in ECG

17

What would make you stop an exercise stress test?

Chest pain, extreme fatigue, dyspnea, leg pain, ST segment changes, dysrhythmias, BP changes, signs og cerebral hypoxia

18

If you see ST segments depression in a pregnant lady, should you assume you immediately assume Ischemia/ MI?

No, the heart gets shifted by the diaphragm being pushed upwards and these changes lead to ECG changes such as ST sagging and T wave Inversion

19

What is High Output HF?

Inadequate perfusion despite normal or elevated CO
- caused by Anemia, Sepsis, Hyperthyroidism, and/or Beri Beri
