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...
normal heart rate range the QT–RRrelation is approximately linear. Heart Rate Correction in Patients with Sinus Arrhythmias If a stable sinus rhythm cannot be obtained in a patient, more advanced methods evaluating repolarization dynam- icity may be required. The QT interval adapts to heart rate ...
During their admission, an striking lengthening of the QT interval, in addition to other criteria of the long QT syndrome, was observed in both patients. We suggest that one normal measurement of the QT interval should not rule out this diagnosis....
QT duration reflects the total duration of ventricular depolarization and repolarization. It is measured from the onset of the QRS complex to the end of the T-wave. The QT duration is inversely related to heart rate; i.e. the QT interval increases at slower heart rates and decreases at high...

QT interval(measured from first deflection of QRS complex to end of T wave at isoelectric line). Normal range up to 440 ms (though varies with heart rate and may be slightly longer in females) Heart rate estimation from the ECG Standard ECG paper ...
Prolongation of the QT interval has been associated with increased vulnerability to ventricular arrhythmias and implicated as a mechanism for the Sudden Infant Death Syndrome (SIDS). Since QT prolongation may result from imbalance of the cardiac sympathe
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...
The QT interval varies ___ to the heart rate. What controls heart rate? 1.)Pulse rate while lying down: a.) Why does it change from the standard pulse rate while at rest? b.) Pulse rate while standing up: c.) Why does it change from the pulse rate while lying down? 2.)Pulse...
