The J wave (== Template:IPA ==
The Template:IPA (International Phonetic Alphabet) is a system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of the sounds of spoken language.
Pronunciation
The pronunciation of the term "IPA" is /aɪ piː eɪ/ in English.
Etymology
The term "IPA" is an acronym for the International Phonetic Alphabet. The International Phonetic Association, founded in 1886, created the IPA to provide a single, universal system for the transcription of spoken language.

- Phonetics: The study of the physical sounds of human speech. It is concerned with the physical properties of speech sounds (phonemes), and the processes of their physiological production, auditory reception, and neurophysiological perception.
- Phonology: The study of the way sounds function within a particular language or languages. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a particular language or languages.
- Transcription (linguistics): The systematic representation of spoken language in written form. The source of the words transcribe and transcription, the term means "to write across" in Latin, and it's the process of converting spoken language into written form.

polski), also known as Osborn wave or camel-hump sign, is a deflection in the ECG tracing that represents a deviation from the baseline in the QRS complex following the QRS and before the ST segment.
Etymology
The term "J wave" was first introduced by John J. Osborn in 1953. The wave is named after him and is also known as the Osborn wave. The "J" in J wave refers to the junction, or the point in the ECG tracing where the QRS complex meets the ST segment.
Clinical significance
The presence of a J wave is often associated with hypothermia and hypercalcemia. It can also be seen in patients with Brugada syndrome, a genetic disorder that can lead to life-threatening arrhythmias.
