Question 1

What are PVC’s?

Answer 1

premature ventricular contractions

• Ventricles firing by themselves

Question 2

EKG for PVC?

Answer 2

Wide QRS without a p-wave and occurs before next predicted QRS complex

Question 3

Hallmarks of PVCs?

Answer 3

Wide QRS without a p-wave

• Palpitations (feeling of like a skipped beat)
• Dizziness
• Asymptomatic

Question 4

Treatment for asymptomatic PVC with no heart disease?

Answer 4

Nada, just MEDADVICE because it could tern into V-Tach or V-Fib

Question 5

Treatment for frequent PVCs and heart disease?

Answer 5

Metoprolol 50mg PO

Question 6

What is V-Fib?

Answer 6

Disorganized firing of the ventricular myocardium with zero cardiac output

Question 7

Hallmarks of V-Fib?

Answer 7

EKG: zig zag pattern without p waves or qrs

• pulseless
• hypotensive
• unconscious

Question 8

Treatment for V-FIB?

Answer 8

ALS protocol for cardiac arrest

Question 9

What type of ventricular tachycardia is Torsades De Pointes?

Answer 9

Polymorphic V-Tach

Question 10

What are some pertinent medical hx for torsades?

Answer 10

Liquid protein diets
Hypothyroidism
Electrolyte imbalance

(Honestly, these could lead to several types of dysrhythmias/cardiac issues)

Sure, these are good to know later on when you get lab work but for now, let’s treat this mother fucker for either stable or unstable. Stable: Magnesium Sulfate 2g IV stat

Unstable: Cardiovert the fuck out of him then follow up with a push of Mag Sulf 2g IV

Question 11

Hallmarks for Torsades?

Answer 11

EKG:

• Wide QRS (remember it’s a vtach arrhythmia)
• V-tach but instead of monomorphic its polymorphic
• Syncope
• Hypotension

Question 12

Treatment for Torsades if stable?

Answer 12

ABCs, Monitor, O2, IV, Vitals

• 2g Magnesium Sulfate IV

Question 13

Treatment for unstable Torsades?

Answer 13

Cardiovert

2g Magnesium sulfate IV

Question 14

Treatment for pulseless Torsades?

Answer 14

ACLS - it’s same same as pulseless Vtach
