EKG Delta and Osbourn Waves in the EKG

Two strange waves that are commonly asked in USMLE exams.

The Delta Wave: Seen Wolf Parkinson White Syndrome which is essentially a slow upstroke of the QRS complex.

The Osbourn Wave: Seen in hypothermia which is an upward deflection between the QRS and the ST segment looking like an ST elevation MI.

Here are two ECG strip delineating the two waves: (click on thumbnails to enlarge)

Thanks, Osbourn waves also known as J waves. We can see them starting from V2.
If you have good things, please do share with everyone.
