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…
Several ECG cases from UMEM that highlight the importance of pattern recognition and a good history to differentiate between benign vs. life threatening ECG findings!
A 76-year-old woman is brought to the emergency department by EMS with for lightheadedness and syncope. The following ECG is obtained on arrival:
