EKG VI: Tech Skills
EKG VI: Tech Skills
Of the following, which ones are reversible?
Ischemia, Injury and Infarction
Ischemia and injury. Infarction is NOT reversible
What would you see with ischemia on an EKG
inverted T, depressed ST segment
What would you see with injury on an EKG
ST elevation
What would you see with infarction on an EKG
Q waves in 2+ contiguous leads, or loss of R waves in precordial leads
This is irreversible cell death caused by prolonged obstruction of arterial blood supply to an area of myocardium
Infarction
What might you see on an EKG that might make you suspect hyperkalemia
Peaked T waves progressing to flattened P waves and prolonged PR interval and finally wide QRS
What might you see on an EKG that might make you suspect hypokalemia
ST depression, flattened T waves, U wave and prolonged QT interval
Define the following for Anterior MI:
1. What leads
2. What you might see
3. What vessel involvment
1. V1, V2, V3, V4
2. ST elevation, T inversion, Q wave
3. LAD (L. anterior descending artery)
Define the following for lateral MI:
1. What leads
2. What you might see
3. What vessel involvment
1. I, aVL, V5, V6
2. St elvation, T inversion, Q wave
3. LCA (L. circumflex artery)
Define the following for Inferior MI:
1. What leads
2. What you might see
3. What vessel involvment
1. II, III, AVF
2. St elevation, T inversion, Q wave
3. RCA (R. coronary artery)
Define the following for Posterior MI:
1. What leads
2. What you might see
3. What vessel involvment
1. V1, V2
2. RICIPRICAL! Large R wave and upright T in V1, V2
3. RCA (R. coronary artery)
How would pericarditis present on an EKG
diffuse (global) ST elevation, concave in appearance, no reciprocal changes, T inversion, no Q's, PR interval depression
How would hypercalcemia present on an EKG
short QT interval
How would hypocalcemia present on an EKG
Prolonged QT interval
How would digoxin toxicity present on an EKG
ST depression with global downward sloping of ST
Can you assess the ST segment or T wave if you have a bundle branch block
NO
What does a Q wave indicate
old or previous MI: takes days to present
Define compensatory
Sinus node doesn't reset. P waves are all normal or march out. PVC may come in but atria ignores it and keeps marching out
Define noncompensatory
PVC resets SA node in Atria
In V1 a notch on the right indicates what
RBBB
in V1 a notch on the left indicates what
V-Tach with ventricular origin
If AVR is in upright direction it may indicate what
V-tach
If AVR is in downward direction it may indicate what
SVT
What is concordance and what does it indicate
when all precordial leads go in same direction: favors ventricular origin
Which heart block is characterized by prolonged PR interval until a QRS complex is dropped
2nd degree AV block type I (Wenckebach)
What characteristics can be seen on EKG with a LBBB
looks normal except for wide QRS; sometimes small R wave, deep S wave
What is a characteristic of WPW
Delta wave
What leads do you interpret for a septal wall MI
V1, V2
