The Osborn wave (J wave) is a positive deflection at the J point (negative in aVR and V1). It is usually most prominent in the precordial leads and most commonly associated with hypothermia.
This review will change your approach to localised ST depression on the ECG, which on its own does not accurately localise ischaemia, and may be the first sign of subtle occlusion
EM attendings are generally faster and more accurate at ECG interpretation than residents and medical students. But how are they able to process this information so much quicker while maintaining accuracy?
Epsilon wave is a small positive deflection buried in the end of the QRS complex on the ECG. Characteristic ARVD arrhythmogenic right ventricular dysplasia
