The purpose of this study was to determine whether J-point elevation is a marker of arrhythmic risk.BackgroundJ-point elevation has been considered an innocent finding among healthy young individuals (the "early repolarization" pattern). However, this electrocardiogram (ECG) finding is increasingly ...
The J wave is a positive deflection in the electrocardiogram (ECG) that occurs at the junction between the QRS complex and the ST segment, also known as the J point. Because much of the J wave is typically hidden inside the QRS, it may manifest as a J point elevation, a slurring of ...
Whatever the terminology which will be further used, either early repolarization (ER), Hai'ssaguerre or J wave syndrome, it should never be forgotten that the ECG pattern associating various degrees of J point elevation, slurring or notching of the terminal part of the QRS and further ST elev...
The J wave, also referred to as an Osborn wave, is a deflection immediately following the QRS complex of the surface ECG, which is usually partially buried inside the QRS, often appearing as a J-point elevation; it represents the end of depolarization and the start of bipolarization [4]....
A large reciprocal ST-segment depression in inferior leads and ST-segment depression in lead V5 are useful ECG findings allowing determination of STEMI due to an LMT lesion. 下导联ST段压低与V5导联ST段压低之间存在较大...
Abstract 3211: Baseline Clinical Risk and Recurrent Ischemia as Detected on Continuous ECG (CECG) Monitoring in Patients with non-ST-Elevation Acute Coronary Syndrome in the MERLIN-TIMI 36 Trial Although analytic techniques commonly used in clinical outcomes trials censor patients who experience a comp...
The same central nervous system autonomic dysfunction has been theorized to produce subendocardial hypoperfusion with electrocardiographic change and cardiac troponin T elevation. This is the first described ECG evidence of a dynamically displaced J-point in the setting of postictal hemiplegia....
Early repolarization (ER) pattern has been recognized for several decades and was interpreted as a variant of the normal electrocardiogram (ECG) as it was frequently observed in young healthy subjects or athletes. It is characterized by a J point elevation and ST-segment elevation inscribed as a...
Since the late 1980s, a renewed interest has emerged in the implications of aberrant terminal R waves and J-ST segments, J point elevation and J waves on the electrocardiogram (ECG) of patients without evidence of gross structural cardiac abnormalities. These implications refer to the association...
A standard 12-lead ECG was recorded at a paper speed of 25 mm/s with amplification of 10 mm/mV in all cases. The J-wave was defined as an elevation in the QRS-ST junction (J-point) of at least 0.1 mV in at least 2 contiguous inferior (II, III, and aVF) and/or lateral (I,...
