HUMAN PHENOTYPE - ANNOTATIONS

The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.

Definition:The J wave is a positive convex deflection that occurs at the junction of the QRS complex and ST segment, the J-point.
Comment:J waves can be seen in hypothermia when the core body temperature falls below 32 degrees C. Then, they occur most prominently in the inferior leads: II, III, and aVF and the precordial leads: V5-V6. J waves can also be observed in other conditions such as some forms of Brugada syndrome.
Synonyms:exact_synonym: EKG J waves;   Osborne waves
