normalQTinterval)-Brugada综合征(短于正常的QT间期)是英文Brugada syndrome (shorter-than的中文翻译。该病是一种基因病、遗传病。佳学基因通过基因解码找到了导致这一疾病发生的基因。可以通过基因检测阻止normalQTinterval)-Brugada综合征(短于正常的QT间期)在后代或者二胎中的出现。根据《人的基因序列变化与人体疾病...

Therefore, normal values for QT interval-heart rate during ramp exercise tests on bicycles were required. Since generally, interval at rest is longer in women than in men both sexes were included in the study. 以局部缺血有夸脱间隔时间甚至延长的较少缩短在锻炼期间。 所以,为夸脱间隔时间心脏率在...

Daytime mean HR gave a mean value of 93 ± 10 (range 71148), while during night hours it was 74 ± 11 (range 5498). The minimum QT interval averaged 261 ± 10 ms for HR> 120 and the maximum 389 ± 9 ms for HR ¤ 60; the corresponding mean value of QTc (i.e., QT corrected...
Symmetrical T waves, upright or inverted as in figure 94-4 above, characteristic of electrocardiographic 'ischemia', are due to cellular affection resulting in prolongation of the action potential reflected in the QT interval. The picture below, figure 94-4b, representing hyperacute ischemia shows ...
Torsade de pointes (TdP) is a life threatening cardiac arrhythmia that is typically associated with prolongation of the QT interval. A wide variety of nonantiarrthymic medications may trigger TdP in patients with prolonged QT interval, only a few reports have described an association between TdP ...
We sought to determine whether the relationship between heart rate (HR) and QT interval (QT) differs as HR increases in response to exercise, atropine and isoproterenol. Background Autonomic nervous system influences on repolarization are poorly understood and may complicate the interpretation of QT ...

The QT interval varies ___ to the heart rate. What is blood pressure? What are the two readings called and what do they indicate about your heart? What is considered to be a normal blood pressure? If your blood volume is 5 L, and each beat of your heart pushes out 70 mL of blood...
