Ekg Criteria

Front 1

LVH

Back 1

1. Add the depth of the S wave in V1 or V2, whichever is deepest, to the height of the R wave in V5 or V6, whichever is the tallest. In order to diagnose LVH, the total must be greater than or equal to 35 mm. In other words: (S in V1 or V2) + (R in V5 or V6) >35 mm.
2. Any precordial lead is >45 mm.
3. The R wave in aVL is > 11 mm.
4. The R wave in lead I is > 12 mm.
5. The R wave in lead aVF is >20 mm.

Front 2

WPW

Back 2

1. Shortened PR interval (<0.12 seconds) with a normal P wave
2. Wide QRS complex (>0.11 seconds)
3. The presence of a delta wave
4. ST-T wave changes or abnormalities
5. Association with paroxysmal tachycardias

Front 3

LBBB

Back 3

1. Duration >0.12 seconds
2. Broad, monomorphic R waves in I and V6, with no Q waves
3. Broad, monomorphic S waves in V1; may have a small R wave

Front 4

RBBB

Back 4

1. QRS prolongation of >0.12 seconds
2. Slurred S wave in leads I and V6
3. RSR' pattern in lead V1, with R' taller than R

Front 5

Pericarditis

Back 5

1. PR depression
2. Diffuse ST elevation
3. Scooping, upwardly concave ST segments
4. Notching of the end of the QRS

Front 6

STEMI Alert

Back 6

1. New or presumably new ST elevation >1 mm in two contiguous limb leads, or in two or more adjacent precordial leads (V1 through V6) with reciprocal depression.
2. New or presumably new left bundle branch block (LBBB).
3. Prominent R waves with ST segment depression >1 mm in V1 and/or V2.

Front 7

Possible hypothermia

Back 7

Osborn waves

Front 8

Hyperkalemia

Back 8

1. T wave abnormalities, especially tall and peaked Ts
2. Interventricular conduction delays (IVCDs)
3. P waves missing or of decreased amplitude
4. ST segment changes simulating an injury pattern
5. Cardiac arrhythmias, any and wall varieties
