1

Treatment for child with coarctation of the aorta presenting in cardiogenic shock?

PGE1 (to keep ductus arteriosus open)

2

Acute Aortic Dissection early Tx:

Esmolol (short acting B1 easily titratable)

3

Prinzmetal's angina.

d/t

EKG findings

Tx

Do not give ____? Why? What other related condition should you not give this med?

Substernal chest pressure at rest and during activity worse in the AM and with smoking.

Dx: Transient ST Elevations on EKG

Tx: CCB, Nitrates

Do not give Propranolol. Unopposed alpha vasoconstriction can cause death. Don't give Propranolol in Intermittent Claudication (for the same reason).

4

EKG findings of myocardial infarction.

Sustained ST elevations (transmural)

Transient or sustained ST depressions

Q waves (Old MI)

5

Digoxin

MOA

What is it used for?

Blocks Na/K ATPase of cardiac myocytes to slow conduction through SA and AV nodes.

For A.Fib

6

Digoxin Toxicity S&S.

 

Antidote?

Yellow vision

Abd pain

2º AV Node Type I (Wenckebach) Block.

 

Tx: Digoxin Immune Fab

7

S&S of Left sided Heart Failure (weeks after Anterior MI.)

 

Most likely caused by?

Dyspnea, crackles

↑ PCWP (> 15) and ↑ RA pressure (>6)

 

d/t Ventricular Aneurysm (ST elevations in V1-V4)

8

What is the 1st line med in all Acute Coronary Syndromes?

Aspirin. (Clopidogrel if unable to tolerate). Reduces morbidity and mortality.

9

Management of Symptomatic A. Fib

 

Dx?

Dx: TEE to check for intracardiac thrombus OR

Anticoagulate for 3 wks before cardioversion

10

LBBB

No R in V1

Tall R in V6

11

RBBB

RSR1 "Rabbit ears"

12

Hypo/Hypercalcemia EKG changes?

Hypocal = "po"longed QT.

Hypercalcemia is opposite (shortened QT)

13
