ECG Variant
Results:
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…
Early Repolarization
Key Points Historical View: Early repolarization (ER) was long considered a benign cause of ST elevation, often called benign early repolarization (BER). Modern View: Certain ER patterns, now termed malignant…
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…
Persistent Juvenile T wave Pattern
Key Points Benign Variant: Persistent juvenile T waves (PJTW) represent a benign ECG finding and require no further evaluation in the absence of clinical symptoms or concerning findings. Typical Distribution:…
Early Repolarization vs STEMI: DDx
Key Points Differentiation Challenge: Early repolarization (ER) is a benign ECG pattern often seen in healthy young individuals, characterized by ST segment elevation that can mimic STEMI and acute pericarditis….
