ST depression is normally due to ischaemia. ST segment depression may also be seen in digoxin toxicity. Here the ST depression will be downsloping (sometimes known as the “reverse tick” sign). NB: High-takeoff A mimic of ST elevation is high-takeoff. High-takeoff is also known as benign...
1. ST depression <0.5 mm 2. T wave inversion <1mm 3. T wave flattening 4. isolated TWI 5. changes that don't meet criteria for dx What is ischemia vs. infarction? ischemia: reversible imbalance of myocardial supply/demand infarction: myocardial cell death ...
ST/T waveDramatic ST depression in V1 – V3 Diagnosis: This is acute posterior MI. What we see in the anterior leads is the equivalent of ‘upside down’ ST elevation. Imagine flipping the ECG paper over and looking at it from behind or looking at the ECG in a mirror held along the...
Significance and Management of Intraoperative Heart Rate – Related EKG ChangesWe searched the electronic records of all anesthetics performed over four years (158,252 cases) for comments including the words "ST depression", "ST elevation", "ST change", "T wave flattening" or "T wave inversion...
ST depression is subendocardial injury T/F Not all ST elevation is bad T. But you must never ignore it Widespread concave ST elevation most prominent in V2-V5, ST elevation usually <2 mm, No reciprocal ST depression, St changes are relatively stable over time ...
This manifests as a TP (really a TQ) segment depression in the leads of the affected territory. .However since EKG machines use the TP segment as the baseline, it corrects for this, moves the baseline up, and with it the ST segments. Hence we see ST segment elevations - even though ...
