ECGs by diagnosis

ACS

• See ACS

Aneurysm

1. Suggested by:
   1. ST elevation >4wk
   2. QS wave in setting of ST-segment elevation w/o T-wave inversion

Pericarditis

• See Pericarditis

Electrolyte Disorders

• Hyperkalemia
• Hypokalemia
• Hypercalcemia
• Hypocalcemia

CNS

1. SAH, IC Bleed, CVA
   1. Diffuse wide, deep, blunted, inverted T waves
   2. QT Prolongation

Pacemakers

1. Should be in the apex of R ventricle
2. ECG should mimic LBBB w/ LAD

Pulmonary Embolism

1. Sinus tachycardia
2. S1Q3T3 (Sp, not Sn)
3. Right axis deviation
4. RBBB
5. T wave inversions leads V1-V3

Hypothermia

1. Osborn wave (J wave) - Positive deflection at the J point
   1. Height of the J wave correlates to the degree of hypothermia
2. Bradyarrhythmias, AV blocks
3. Prolonged PR, QRS, QT intervals
4. Shivering artifact
