Q
  1. Is this shit sinus?
    - Look for the P; if there is a P wave, there is a sinus rhythm. Best place to look for lead 2 and V1. If there is, it is a sinus rhythm and it excludes MANY rhythms. “you always want to put the P in the V1

Q

How can we tell the difference between hyperkalemia and STEMI?

A

Hyperkalemia: peaked T-wave “sharp at the top”; someone just grabbed the T-wave and pulled it up.

STEMI: more round/blunted bc S-T is elevated

Q

What is the PR interval?

A

Distance from begining of P wave -> begining of QRS.

17
Q

What do we see in a 1st degree AV block?

A

- Prolonged PR intervals (>200ms/5 boxes)

18
Q

2nd degree AV blocks can be…

A
  • 1. Mobitz 1 (Wenkebach)
  • 2. Mobitz 2
19
Q

What does a 2nd degree AV block (Wenkeback/Mobitz 1) look like?

A

Progressively long PR intervals (PR >200ms), then a QRS segment is dropped.

“longer, longer, longer DROP, that is a Wenkebach”

20
Q

What does a 2nd degree AV block (Mobitz 2) look like?

A
  • Prolonged PR >200 (WITHOUT GETTING PROGRESSIVELY LONGER) => QRS drop.
  • Like a type 1, without a drop.
21
Q

What is a 3rd degree AV block?

A

Atria and ventricles are contracting INDEPENDTLY; both work and squeeze.

Finding:

  • - Constant P-P intervals
  • - Constant Q-Q intervals
  • however, bc they are independent of one another, the P waves can be burried in QRS complex
22
Q

What sx do people with AV block experience?

A
  • Bradycardia
  • Dizziness
  • Syncope
