从实验性力量练习后即刻采集的ECG数据中发现,当人体经大力量负重蹲腿起后,J点下移(downwarddisplacementofJpoint)、S-T段平直延长(S-Tsegmentftatstraightprolongation)、大于50%,和Q-T比值,以及Q-Tc都增大,作者认为是练习后心肌缺血缺氧,电解质紊乱细胞内K+浓度升高,血钙过低、除极波受阻引起损伤电位以及心内膜...
本发明涉及定位心电图信号中的J点.当前主题通过检验S峰和T峰之间的样本窗口内的ECG样本来确定ECG信号中的J点的位置.选择该范围中具有到R峰的最小距离Δd的样本作为J点.因此,可以基于ECG样本至R峰的距离来确定J点的位置.然后J点位置可以用于确定是否存在ST段的抬高或压低.还描述了相关装置,系统,技术,和商品.收...

Schema of the measurement of ECG intervals evaluated in the study: Panel (A) shows all 12 leads of an ECG sample superimposed on the same isoelectric axis. Using images of this kind, QRS complex onset (red line), J point (i.e. QRS offset, amber line) and T wave offset (green line...
Body proportions of circumpolar peoples as evidenced from skeletal data: Ipiutak and Tigara (Point Hope) versus Kodiak Island Inuit Given the well-documented fact that human body proportions covary with climate (presumably due to the action of selection), one would expect that the Ipiut... TW...
DEFINITIONS The term "J wave" (or Osborn wave) was intro- duced 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 ...
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...
