Osborn Wave (J Wave) • LITFL • ECG Library Basics
Jan 1, 2022 · The Osborn wave (J wave) is a positive deflection seen at the J point in precordial and true limb leads. It is most commonly associated with hypothermia. These changes will appear as a reciprocal, negative deflection in aVR and V1.
ECG J wave syndromes: hypothermia, early repolarization ...
J waves are typically most pronounced in the anterolateral (V3, V4, V5, V6) and inferior (II, aVF and III) leads. There are four principal causes of J waves, namely hypothermia, Brugada syndrome, early repolarization and hypercalcemia.
Early repolarization - UpToDate
May 16, 2022 · The term early repolarization (ER), also known as "J waves" or "J-point elevation," has long been used to characterize a QRS-T variant on the electrocardiogram (ECG). Most literature defines ER as being present on the ECG when there is J-point elevation of ≥0.1 mV in two adjacent leads with either a slurred or notched morphology.
J Wave Syndrome: Clinical Diagnosis, Risk Stratification and ...
Dec 31, 2014 · J wave is an ECG finding and not a clinical sign or symptom. The only known manifestation symptom is sudden cardiac death (SCD) or VF. Benign versus malignant morphological features of J wave are described yet sometimes dynamic variability of J wave shape especially in setting of CAD is intriguing. Benign J waves are prominent among young ...
J point ECG Interval • LITFL • ECG Library Basics
Apr 7, 2023 · The J point is a point in time marking the end of the QRS and the onset of the ST segment present on all ECG’s; the J wave is a much less common long slow deflection of uncertain origin originally described in relation to hypothermia.
Hypothermia ECG changes • LITFL • ECG Library Diagnosis
Oct 8, 2024 · Patients may manifest a variety of bradyarrhythmias: ECG with the classic features of hypothermia: bradycardia, Osborn waves and shivering artefact. The Osborn wave (J wave) is a positive deflection at the J point (negative in aVR and V1). It is usually most prominent in the precordial leads.
J wave syndromes - Heart Rhythm
The J wave, also referred to as an Osborn wave, is a deflection immediately following the QRS complex of the surface ECG. When partially buried in the R wave, the J wave appears as J-point elevation or ST-segment elevation.
J-Wave Syndromes - Cardiac Electrophysiology Clinics
The term “J wave” (or Osborn wave) was introduced to describe a positive J-point deflection at the end of the QRS complex. 1 In 1953, Osborn first associated this electrocardiogram (ECG) pattern, defined as “current of injury” (from which the “J” originates), with the onset of arrhythmias and ventricular fibrillation (VF) during ...
J wave syndrome: Benign or malignant? - PMC
Oct 2, 2020 · Growing evidence suggests that despite the differences of BrS and ERS in terms of the magnitude of J wave abnormality and location of ECG presentation, they are actually different points in a spectrum known as J wave syndrome.
J Wave - an overview | ScienceDirect Topics
J waves, defined as an elevation of the QRS-ST junction ≥1 mm either as QRS slurring or notching, are a hyperacute sign of TTS with a prevalence of 16%–26% on the admission ECG (Fig. 35.2D) [33, 34, 42].
