ECG Variant
Results:
STEMI vs Early Repolarization: DDx
Key Points: Early repolarization (ER) is one of the most common non-ischemic causes of ST elevation and one of the most frequent ECG mimics of acute anterior coronary occlusion. The…
Early Repolarization
Key Points: Definition: Early repolarization (ER) is a common ECG pattern characterized by J-point elevation, often with concave ST elevation and J-wave notching or slurring. Clinical importance: ER is one…
Persistent Juvenile T Wave Pattern
Key Points: Persistent juvenile T wave pattern is a benign normal variant that most often appears as shallow asymmetric T wave inversion in the right precordial leads, usually V1 to…
Pseudo-Wellens Waves
Key Points: Pseudo-Wellens waves are anterior T-wave patterns that mimic the biphasic or deeply inverted T waves of true Wellens syndrome but are caused by non-LAD, non-ischemic physiology. These normal-variant…
Terminal QRS Distortion: OMI Pattern
Key Points: What it is: In V2 or V3, there is no S wave (the R does not descend below the PQ baseline) and no J wave (no notch/slur at…
Dextrocardia
Key Points Dextrocardia is a congenital condition where the heart is located on the right side of the thorax. Situs inversus totalis refers to complete reversal of all thoracic and…
