Card Set Information
12 Lead Interpretation
I, aVL (Top)
V5, V6 (Middle)
What is the steps to the systematic approach to reading a 12-Lead?
Baseline ECG (Normally Lead II)
Bundle Branch Blocks
Assess for Infarct (I See All Leads)
Normal Axis Determination in I, II, III
Left Physiological Axis Determination
Left Pathological Axis Determination
Right Axis Determination
Extreme Right Axis Determination
What is the "Turn Signal Rule"?
J Point, points up - Right BBB
J Point, Points down - Left BBB
3- MI Pitfalls in 12-Lead Interpretation
Left Ventricular Hypertrophy
How do you determine Left Ventricular Hypertorphy (LVH)
The R wave in lead aVL is taller than 12mm or
Rule of 35
Rule of 53
What is the Rule of 35/53?
Look at the tallest R wave in V4, V5, or V6
Add the total mm of R wave to Deepest S wave in V1, V2, or V3
If the total is >35 and the Pt is >35 it is LVH
If <35 yo, use rule of 53
How do you determine Pericarditis?
ST Elevation in most leads
Pt. will feel better when leaning forward
No ST Depression
What factors determine true V-Tach on a 12-Lead?
Leads I, II, and III all Down? Yes V-Tach
Is V1 Up? Yes V-Tach
Is V6 Down? Yes V-Tach
What does "I See All Leads" the acronym for?
Deviations in leads II, III and aVF
Deviations in leads V1 and V2
Deviations in leads V3 and V4
Deviations in leads V5, V6, I, aVL
