EKG VI: Tech Skills

Front 2

Of the following, which ones are reversible?
Ischemia, Injury and Infarction

Back 2

Ischemia and injury. Infarction is NOT reversible

Front 3

What would you see with ischemia on an EKG

Back 3

inverted T, depressed ST segment

Front 4

What would you see with injury on an EKG

Back 4

ST elevation

Front 5

What would you see with infarction on an EKG

Back 5

Q waves in 2+ contiguous leads, or loss of R waves in precordial leads

Front 6

This is irreversible cell death caused by prolonged obstruction of arterial blood supply to an area of myocardium

Back 6

Infarction

Front 7

What might you see on an EKG that might make you suspect hyperkalemia

Back 7

Peaked T waves progressing to flattened P waves and prolonged PR interval and finally wide QRS

Front 8

What might you see on an EKG that might make you suspect hypokalemia

Back 8

ST depression, flattened T waves, U wave and prolonged QT interval

Front 9

Define the following for Anterior MI:
1. What leads
2. What you might see
3. What vessel involvment

Back 9

1. V1, V2, V3, V4
2. ST elevation, T inversion, Q wave
3. LAD (L. anterior descending artery)

Front 10

Define the following for lateral MI:
1. What leads
2. What you might see
3. What vessel involvment

Back 10

1. I, aVL, V5, V6
2. St elvation, T inversion, Q wave
3. LCA (L. circumflex artery)

Front 11

Define the following for Inferior MI:
1. What leads
2. What you might see
3. What vessel involvment

Back 11

1. II, III, AVF
2. St elevation, T inversion, Q wave

2. What you might see
3. What vessel involvment

Back 12

1. V1, V2
2. RICIPRICAL! Large R wave and upright T in V1, V2
3. RCA (R. coronary artery)

Front 13

How would pericarditis present on an EKG

Back 13

diffuse (global) ST elevation, concave in appearance, no reciprocal changes, T inversion, no Q's, PR interval depression

Front 14

How would hypercalcemia present on an EKG

Back 14

short QT interval

Front 15

How would hypocalcemia present on an EKG

Back 15

Prolonged QT interval

Front 16

How would digoxin toxicity present on an EKG

Back 16

ST depression with global downward sloping of ST

Front 17

Can you assess the ST segment or T wave if you have a bundle branch block

Back 17

NO

Front 18

What does a Q wave indicate

Back 18

old or previous MI: takes days to present

Front 19

Define compensatory

Back 19

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

Front 20

Define noncompensatory

Back 20

PVC resets SA node in Atria
