The characteristic ECG findings in the Wolff-Parkinson-White syndrome include a slurred upstroke to the QRS complex (the Delta wave)
The Osborn wave or J wave is a positive deflection at the J point (negative in aVR and V1) LITFL ECG Library basic interpretation
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.
T wave abnormalities include Peaked T waves, Hyperacute T waves, Inverted T waves, Biphasic T waves, ‘Camel Hump’ T waves, Flattened T waves
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
