A traceable time interval measurement with a reduced uncertainty
International Journal of Metrology and Quality Engineering, 2015 Time interval (TI) is one of the basic quantities. Its measurement is not included only in the activities running in the time and frequency metrology but also included in the measurement of many other quantities that depend on time ...

A New Automatic QT-Interval Measurement Method for Wireless ECG Monitoring System Using Smartphone [PDF]
Journal of Biomedical Physics and Engineering, 2021 QT-interval prolongation is an important parameter for heart arrhythmia diagnosis. It is the time interval from QRS-onset to the T-end of electrocardiogram (ECG). Manual measurement of QT-interval, especially for 12-leads ECG, is time-consuming.
