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...
Heart rate, QT interval variability and rate adaptation in pregnancies with AP-NO respectively PO The average RR interval was significantly different between the three groups of pregnant women (Figure 1a; Po0.0001). Post-hoc analysis revealed the prolongation of RR intervals in AP-NO in comparison...
In comparison to men, women had more negative HR-QT slopes during all interventions. At 100 beats/min, the QT was 364 ms during isoproterenol, which was significantly longer than that during exercise (330 ms) or atropine (339 ms) (p < 0.0001). Isoproterenol produced a dose-dependent ...
The HR-QT slope (ms/beats/min) was less steep for isoproterenol (−0.83 ± 0.53) than for atropine (−1.45 ± 0.21) or exercise (−1.37 ± 0.23) (p < 0.0001). In comparison to men, women had more negative HR-QT slopes during all interventions. At 100 beats/min, the QT was...
HR - Heart rate; bpm - beats per minute; ms - milliseconds; PRI – PR interval; QTI – QT interval; QTIc - QT interval corrected. Women showed higher median heart rate values, as well as the QT interval corrected by the Hodges, Bazzet, Fridericia and Framinghan formula, while men disp...
During sinus rhythm with normal rates the QT interval is short (Fig. 94-29a bottom). If factors known to modify the QT are not present, it has been said that a reasonably accepted correlation exist between the duration of the interval and serum calcium levels. The primary manifestation of ...

The criteria established for prolonged QTc were: Age < 40 years, men 430 ms, women 440 ms; Age 40 to 69, men 440 ms, women 450 ms; Age ≥ 70 years, men 455 ms, and women 460 ms. Conclusions Sex difference in QTc originates from shortened QT in adolescent...
