Web3. Results. The QTc duration in the fifth percentile is relatively stable across all ages, until the age of 85 years, when there is a rise in men and an apparent reduction in women (Fig. 1).These changes in the older age groups of both genders are most likely due to the presence of a smaller part of the population at the older age being in the lower percentile … An "abnormal" QTc in males is a QTc above 450 ms; and, in females, above 470 ms. [17] If there is not a very high or low heart rate, the upper limits of QT can roughly be estimated by taking QT = QTc at a heart rate of 60 beats per minute (bpm), and subtracting 0.02 s from QT for every 10 bpm increase in heart rate. Ver más The QT interval is a measurement made on an electrocardiogram used to assess some of the electrical properties of the heart. It is calculated as the time from the start of the Q wave to the end of the T wave, and approximates … Ver más The QT interval changes in response to the heart rate - as heart rate increase the QT interval shortens.
