J wave

A J wave occurs just after the QRS complex at the J point. If small, it is also known as J point notching or the Fishhook sign. Larger J waves are known as Osborn waves.

A Young Man with Sharp Chest pain

This ECG is from a teenage male who had a seizure.

This ECG shows diffuse ST elevation with prominent J waves and no reciprocal ST depression. The most likely cause was early repolarisation.

Three EKGs shown to me – which if any need emergent reperfusion?

This ECG is from a man in his 30s with unknown symptoms.

This ECG shows ST elevation (false positive) with clear J waves. Angiogram, troponins and serial ECGs were normal.

Two cases of ST Elevation with Terminal T-wave Inversion – do either, neither, or both need reperfusion?

This ECG is from a teenage male who presented with chest tightness and shortness of breath for 6 hours on a background of asthma.

This ECG shows sinus rhythm with tall QRS and associated repolarisation changes, benign T wave inversion in V3-V6 with J-waves and ST-elevation.
