Vad betyder Högerställd Elaxel?
En högerställd el-axel kan orsakas av högerkammarhypertrofi eller högerkammarbelastning, ex sekundärt till lungemboli. En vänsterställd el-axel beror ofta på främre fascikelblock. När QRS-komplexen är övervägande negativa i avledning I och II är den vanligaste orsaken felplacerade EKG-elektroder.
Vad betyder reciproka ST-sänkningar?
– ST höjning i inferiora avledningar (II, aVF, III). – I laterala avledningar (aVL, I) ses reciproka ST-sänkningar, d v s spegelbild till inferior ST-höjning. – Sinusrytm, frekvens 73 slag/min.
What is an inferior wall ST segment elevation?
Inferior Wall ST Segment Elevation Myocardial Infarction (MI) ECG Review. An inferior wall myocardial infarction — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.
What is inferior ST elevation myocardial infarction?
Inferior ST Elevation Myocardial Infarction. Inferior MI accounts for 40-50% of all myocardial infarctions. Generally have a more favourable prognosis than anterior myocardial infarction (in-hospital mortality only 2-9%), however certain factors indicate a worse outcome.
How long does ST elevation last after an inferior MI?
There is still some residual ST elevation in the inferior (II, III, avF) and lateral (V5-6) leads. ST elevation may take 2 weeks to resolve after an acute inferior MI (even longer for an anterior STEMI) NB. If this patient had ongoing chest pain you would still treat them as an acute STEMI!
What does ST elevation of 2mm indicate?
ST elevation is also present in the lateral leads V5-6, indicating an extensive infarct of the inferior and lateral walls. In patients with inferior STEMI, ST elevation of 2mm or more in leads V5 and V6 is predictive of extensive coronary artery disease and a large area of infarction.
