A normal corrected QT interval (QTc) duration is typically considered under 430 milliseconds for an adult male and under 450 milliseconds for an adult female after correction. If you want to determine the QTc of a patient, you can use the Omni QTc calculator. What is QTc prolongation? A pro...

Based on the length of QTc interval measurement in 12lead conventional electrocardiography, the study subjects were divided into the normal QTc interval group (423 cases) and the prolonged QTc interval group (145 cases), and the general data and laboratory tes...
4、 QTc dispersion before and after exercise in normal controls (P0.05).Conclusion:Results revealed that increased QTc dispersion might result from myocardial ischaemia during exercise test. It could serve as an indicator to judge result in exercise stress test.Key words:Myocardial ischaemiaQTc dispers...

这个直接映射的部分, 就是所谓的 NORMAL 区, 也就是所谓低端内存,而动态映射的部分,就是所谓高端内存。到了 64位时代,内核空间大大增大,这种限制就没了,内核空间可以完全进行线性映射,不过,基于某种原因,仍保留有动态映射这部分: 动态映射不全是为了内核空间可以访问更多的物理内存,还有一个重要原因:当内核需要连续...
1:在normal模式下,用h表示向左移动光标,用j表示向下移动光标,用k表示向上移动光标,用l表示向右移动光标。 2:w是“word”的首字母。表示向后移动到下一个单词的首字母上,不管当前光标是在一个单词的开头、中间还是结尾。比如下面的例子: hello, this is only atext,please ignore it. ...
(AS),and 30 normal subjects. Results QTd and QTcd are significantly greater in group EH,HCM and AS than normal group(P<0.01),HCM and AS were greater than EH(P<0.05 and P<0.01,P<0.05 and P<0.01),no significantly different between HCM and AS. Conclusion QTd and QTcd may be a ...
