Osborn Wave (J 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

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.

P wave

The P wave on the ECG. The P wave is the first positive deflection on the ECG and represents atrial depolarisation. Duration: < 0.12 ms (<120ms or 3 small squares)

T wave

T wave abnormalities include Peaked T waves, Hyperacute T waves, Inverted T waves, Biphasic T waves, ‘Camel Hump’ T waves, Flattened T waves
