ST elevation
What is ST elevation? what are the dangers involved and what actions to be taken? please help me to find answers for one of my friends is having this
ST is an electrical wave form that has different tracings on graph output of an electrocariogram depending on which of 12 leads placed on the chest to view the electrical impulses from different angles as the impulse passes through different portions of the heart. Just an ST elevation is undefined and non-specific and requires more information in relation to other wave forms and symptoms with further testing for an abnormal EKG.
It can be any of the following:
Injury (Acute MI, heart attack) ST "Elevation"; often with Q waves; often with T wave inversion
Vasospasm usually lasts minutes (Prinzmetal's/Variant Angina,.. chest pain)
Ventricular aneurysm usually post-MI; long-standing ST elevation in Q wave leads
Pericarditis (inflammation of the area covering the heart) often ST concave upward; young, non-CAD (no coronary artery blockage) pateint's
Pseudo MI acute GI disturbance (cholecystitis, pancreatitis); acute 'lyte changes; very rare
Early Repolarization (rhythm significance) normal in youths; usually V2-V3; often J point notch;
exercise normalizes
Artifact may be seen following large S waves (e.g., in LVH); ignore if isolated in V2
