ACS

See ACS

Aneurysm

see Left ventricular 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

Pacemakers

see Pacemaker complication

  • Should be in the apex of R ventricle
  • ECG should mimic LBBB with LAD

Pulmonary Embolism

see Pulmonary embolism

  • Sinus tachycardia
  • S1Q3T3 (Sp, not Sn)
  • Right axis deviation
  • RBBB
  • T wave inversions leads V1-V3

Hypothermia

see Hypothermia

Osborn wave.gif
  • 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
