ACS
See ACS
Aneurysm
- Suggested by:
- ST elevation >4wk
- QS wave in setting of ST-segment elevation with out T-wave inversion
Pericarditis
See [[Pericarditis*ECG|Pericarditis]]
Electrolyte Disorders
CNS
- SAH, IC Bleed, CVA
- Diffuse wide, deep, blunted, inverted T waves
- QT Prolongation
Pacemakers
- Should be in the apex of right ventricle
- ECG should mimic LBBB with LAD
Pulmonary Embolism
- Sinus tachycardia
- S1Q3T3 (Sp, not Sn)
- Right axis deviation
- RBBB
- T wave inversions leads V1-V3
Hypothermia
- Osborn wave (J wave) - Positive deflection at the J point
- Height of the J wave correlates to the degree of hypothermia[1]
- Bradyarrhythmias, AV blocks
- Prolonged PR, QRS, QT intervals
- Shivering artifact
