Q

When is it indicated to start thrombolytics and PCI?

A

1) Must do PCI in less than <90 minutes if available on site
2) If PCI is not available on site, transfer to a neigboring hospital <120 minutes (still better than thrombolytics)
3) ONLY when the PCI ETA is >120, then you administer them (IV Heparin, Enoxparin) and then you STILL transfer to a hospital for a PCI

Q

When is sinus bradycardia most common and do you need to treat it?

A

When you get an inferior MI or with meds

Nah, only temporary pacing and that’s rarely required

29
Q

How do you treat post MI SVT/A fib?

A

Rate controlling agents like metoprolol or CCB if there is a contraindication to beta blockers

Q

How do you treat if the patient is hypotensive with severe chest pain and HF?

A

Amiodarone

Shock them

31
Q

Where are the most common conduction problems?

A

At the level of the AV node and less commonly distal/infra nodal to the AV node

32
Q

What is the treatment for first degree AV block?

A

Sike, it does not require treatment

33
Q

What is the treatment for second degree AV block?

A

Sike, it does not require treatment unless they’re very symptomatic

34
Q

What is the treatment for complete AV block and when do they most commonly occur?

A

Occurs most with inferior MIs

Prognosis is worse with ant MI

Requires permanent pacing

Intra aortic balloon pump

Surgery is a definitive treatment

42
Q

43
Q

3) Tachycardia

Could have altered mental status

51

A

1) Get coronary angiography
2) Possible placement of intra aortic balloon pump

52
Q

What is hypovolemic shock a result of?

Decreased intravascular volume secondary to loss of blood or fluids due to dehydration or hemorrhage

53

Treat underlying condition

56
Q

A

Septic shock

57
Q

What is septic shock?

A

Sepsis with fluid unresponsive hypotension and serum lactate level > 2mmol/L and a need for vasopressors to keep mAP above 65 mm Hg (bc there is systemic vasodilation)

58
Q

What is the most common cause of septic shock?

A

Infection with gram positive or gram negative bacteria

59
Q

How do you generally approach shock?

60
Q

What are the hemodynamic measurements associated with cardiogenic shock?

A

1) Reduced Cardiac Output (CO)
2) Reduced Cardiac Index (CI)

*(Cardio shock is a central process with aggressive vasoconstriction)*

61
Q

What are the hemodynamic measurements associated with septic shock?

A

1) CO, CI may be initially elevated or normal but in severe cases CO and CI can be decreased due to myocardial depression
2) Low SVR, CVP, PCWP

*Aggressive vasodilation*

62
Q

What are the most important treatments to septic shock?

A

Since they’re in hypovolemic shock you must give fluids and vasopressors (NE, dopamine, vasopressin) Then IV antibiotics to treat infection
