medications

Answer 3

Pacing + Atropine

Question 4

Tachycardia + Hemodinamically unstable

Treatment

Answer 4

Cardioversion (Synch.)

Question 5

VT in the following scenarios:
1. Stable?
2. no P waves?
3. Unstable?

Answer 5

1. Amioderone
2. Unsychronized Cardioversion- VF?
3. sychronized Cardioversion

Question 6

SVT

treatment

Answer 6

Vagal –> Adenosine –> BB or CCB

Question 7

Afib/AFlutter
1. Unstable & new Afib (< 48h)?
2. everything else?

treatment in following scenarios:

Answer 7

1. Sync. Cardioversion
2. anticoagulation and others

Question 8

MAT (Multifocal atrial tachycardia)
1. how to diagnose on ECG?
2. Treatment?
3. Avoid?

Answer 8

1. > 3 p waves morphologies
2. treat: CCB
3. Avoid: Beta-Blockers

seen on COPD patients

Question 9

Heart Block
first
Second
Third
and treatment

Answer 9

1. First- PR > 120 ms
2. Second type I - PR longer and longer until drop QRS
3. Second type II (morbitz 2)- PR prolongation fixed and fix amount of QRS dropped.
4. Third- no relations between P and QRS complexs. P-P interval equal

Treatment:
Morbitz < 2 = observation
Morbitz > 2 = Pacemaker

Question 10

Torsade Treatment

Answer 10

Magnesium

Question 11

WPW
ptognemonic fetaure?
treatment (Stable vs. unstable)

Answer 11

1. Delta P waves + Short PR, wide QRS (in young)
2. Stable- Procinamide (Ia) - can cause Drug induce lupus
   Unsatble- Syn. Cardioversion

Question 12

TCA toxicity
on ecg finding
and treatment

Answer 12

Sinus Tachy + Prolongation of PR (AV block type I), QRS (wide) QT.

Treatment: Sodium Bi-carbonate

Question 13

ECG & electrolytes:
Hypo
Hyper

ECG feature

Answer 13

Hypo- Prolong QT
Hyper- Short QT
Hyperkalemia- Tall T waves + wide QRS
