Vad är STEMI och Nstemi?
De viktigaste diagnoserna är stabil angina och akuta koronara syndrom som i sin tur delas upp i ST-höjningsinfarkt (STEMI) och instabil kranskärlssjukdom. Den sistnämnda omfattar instabil angina och icke ST-höjningsinfarkt (NSTEMI).
What is ST segment elevation and ST segment deviation?
The ST segment may be displaced upwards (ST segment elevation) or downwards (ST segment depression). The term ST segment deviation refers to elevation and depression of the ST segment. The magnitude of ST segment deviation is measured as the height difference (in millimeters) between the J point and the PR segment.
What are the causes of ST elevation?
Other causes of ST elevation include: 1 Coronary Vasospasm (Prinzmetal’s Angina) 2 Acute Pericarditis: typically causes diffuse ST elevation associated with PR depression (reciprocal ST depression and PR elevation seen in leads aVR and V1) Benign Early Repolarization: mild ST elevations with 3 Left Bundle Branch Block
What does it mean when your STS are elevated?
When ST elevation is present, it is most important to rule out cardiac ischemia or a myocardial infarction. Other causes of ST elevation include: Benign Early Repolarization: mild ST elevations with tall T waves, mainly in the precordial leads
What is STST elevation in ECG?
ST elevation refers to a finding on an electrocardiogram wherein the trace in the ST segment is abnormally high above the baseline. The ST segment starts from the J point (termination of QRS complex and the beginning of ST segment) and ends with the T wave.
Om infarkten leder till döden är dödsorsaken oftast ventrikelflimmer, det vill säga flimmer i en hjärtkammare, som kan uppstå när som helst under hjärtinfarktförloppet. Experterna skiljer på hjärtinfarkt med ST-höjning på EKG (STEMI) och hjärtinfarkt utan ST-höjning (NSTEMI).
