One such high-risk ECG pattern includes the association of the prominent T wave and J-point depression producing ST-segment depression seen in the precordial leads coupled with ST-segment elevation in lead aVr. This ECG presentation is associated with significant left anterior descending artery ...
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. From: Cardiac Electrophysiology: From Cell to Bedside (Sixth Edition), 2014 ...
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 ...
27obtaining Food and Drug Administration (FDA) approval in 1997, then for resistant depression,28with hundreds of thousands of devices implanted all over the word and a very good safety profile.
The article reports that researchers in Denmark have found that bullying among children is associated with a high incidence of depression in middle-aged men. A 2004 survey of men from a 1953...
Thus, the J-point location can be determined based on an ECG sample's distance to the R-peak. The J-point location can then be used to determine whether there is elevation or depression of the ST segment. Related apparatus, systems, techniques, and articles are also described.Zhe Zhang...
After 30 hours, the benefit on the primary end point plateaued through 48 hours. Major bleeding and transfusion requirements, not related to coronary bypass surgery, were not associated with time of catheterization. Tric...
The surface ECG demonstrated no discernible ST-T changes but distinct J waves in the inferior leads (Fig. 1). Short-coupled repetitive PVBs (Fig. 1) and the gradual appearance of J waves (Fig. 2) were observed during an increase in ACh dose from 10 to 100 μg. Since there was no ...
For ST depression or elevation ≥0.05 mV in lead LIII, agreement was good and moderate (κ = 0.79 and 0.51, respectively). Bland-Altman analysis demonstrated clinically acceptable limits of agreement comparing measurements of the J point and the T wave, but clinically inadequate limits of ...
Patients with anginal chest pain lasting > 10 minutes were eligible for enrollment if at least one of the following was present: new ECG ST depression: transient ST elevation: elevated troponin or CKMB; known CA...
