Osborn Wave (J Wave)
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.
Tag ECG Waves
Delta Wave
The characteristic ECG findings in the Wolff-Parkinson-White syndrome include a slurred upstroke to the QRS complex (the Delta wave)
U Wave
The U wave is a small (0.5 mm) deflection immediately following the T wave, usually in the same direction as the T wave. Best seen leads V2 and V3.
R wave
On this page we will discuss and provide examples of R wave abnormalities such as Dominant R wave in V1, aVr and PRWP LITFL ECG Library
Q Wave
Q Wave morphology and interpretation. A Q wave is any negative deflection that precedes an R wave. LITFL ECG Library
