Q

How do we describe different A Flutter rhythms?

A

rate of flutter to QRS can range from 1:1 (fastest) to 2:1….4:1 (slower as numbers go up)

30
Q

Rate 20-40

A

Idioventricular

31
Q

What’s the difference between Idioventricular and Junctional Escape

A

Idioventricular has a wide QRS
Junctional Escape may have an inverted P

32
Q

Toxicology or metabolic signs in ECG

A

Regular rhythm
Wide qrs complex over 200ms
Ventricular rate 120 (still too slow to be a vtach), i.e. = super wide but not too fast

33
Q

V2-V3 - Pattern of inverted or biphasic T waves (the T starts on positive, goes negative, goes back to positive)
No precordial q waves

A

Wellens’ syndrome
* Indicative of upcoming MI in days

34
Q
  • P wave with two humps
  • Conduction from SA node, first impacts the right atrium than to LA via Bachmann’s bundle. If there is a delay due to ischemia it will look like double humps
A

P mitral “mit ral”

35
Q
  • P wave looks like a tall triangle.
  • Suggests right heart problem
  • Right heart problems are usually pulmonary related
A

P Pulmonale

36
Q

Lateral leads

A

I, aVL, V5, V6

37
Q

Inferior leads

A

II, III, aVF

38
Q

Anterior & Septal leads

A

V1, V2 are both Septal and Anterior
V3, V4 are Anterior

39
Q

First look in ACG

A
  • Inf leads first - most common MI in the US (II, III, aVF)
  • V5 and V6 - Lateral lower - deadliest
  • In V3 and V4, a little V2 - anterior - widow maker
40
Q

Looking at the limb leads (first six)

A

=>1mm STE (Leads: I, II, III, AVR, AVL, AVF) in two or more contiguous leads

41
Q

Looking at leads V1-V6

A
  1. V1,V4-V6 (over 2mm), not involving V2-V3
  2. V2-V3 (over 2mm for men, 1.5mm women)
42
Q

ST depression in greater or equal to 2 precordial leads V1-V4

A

Posterior wall impact

43
Q

Pathological q waves

A
  • Greater than 1mm wide
    • Greater 2mm deep
    • Greater than 25% of the qrs depth
44
Q

Axis deviation ranges

A

Normal is between -30 and +90 degrees; Extreme axis deviation -90 to -180

45
Q

Distinguishing RBBB & LBBB

A

Both will have supraventricular rhythm (mainly NSR); can be Afib/Aflutter
Wide QRS .12<
Look at V1-V3
If pronounced Q pointing negative = LBBB (most common)
If pronounced R positive (likely notched) = RBBB
