The J point of the ECG is at the end of the QRS complex and the beginning of the ST segment. J point elevation can be seen in early repolarization. At times, J point elevation can be ischemic, however, this is somewhat rare.Enlarge ...
ECG, interpretationIntroduction and objectives Identification of the J-point and measurement of ST segment elevation at the J-point are important for the diagnosis of ST-elevation myocardial infarction (STEMI). We conducted a study to determine the inter-rater reliability (IRR) of J-point location...
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. Several lines of evidence have suggested that arrhythmias associated...
However, it is not always easy to confirm that the culprit lesion is an LMT lesion, based only on initial ECG findings; it is especially difficult to distinguish an LMT lesion from a left anterior descending artery ...
entities, namely Brugada syndrome (BrS) and early repolarization syndrome (ERS).2,3 Their common manifestation is the presence of electrocardiographic abnormalities involving the terminal part of the QRS complex at the transition point with the ST segment, that is, the J point in the normal ECG....
Recent studies suggest that the electrocardiographic (ECG) finding of J-point ST-elevation, the early repolarization syndrome, is not as benign as earlier ... SMD Shlomo - 《Annals of Noninvasive Electrocardiology》 被引量: 30发表: 2011年 ...
point. Middle part of IVS demonstrates ST-segment elevation without significant activation delay, whereas nonischemic LV apex shows no changes. (B) LAT medians (lines), interquartile range (boxes), mean (crosses) and limits (error bars) in different myocardial regions at baseline and 5 min...
An early repolarization (ER) pattern in the ECG, distinguished by J-point elevation, slurring of the terminal part of the QRS and ST-segment elevation has long been recognized and considered to be a benign electrocardiographic manifestation. Experimental studies conducted over a decade ago suggested...
J wave syndromes are characterized by J point and ST-elevation in distinct ECG leads. The region most affected by BrS is the anterior right ventricular outflow tract, accounting for why J point and ST segment elevation are limited to the right precordial leads. The region most affected in ...
J point elevationInterest in early repolarization (ER) increased after the theoretical proposal1 and the clinical demonstration2 that certain electrocardiographic (ECG) patterns characterized by an elevation of the J point were associated with an increased risk of sudden cardiac death in otherwise ...
