J wave

A J wave — also known as Osborn wave, camel-hump sign, late delta wave, hathook junction, hypothermic wave,[1] K wave, H wave or current of injury — is an abnormal electrocardiogram finding.[2]

J waves are positive deflections occurring at the junction between the QRS complex and the ST segment,[3][4] where the S point, also known as the J point, has a myocardial infarction-like elevation.
