The maternal heart significantly adapts to the circulatory needs of pregnancy, but the effect of pregnancy on ventricular repolarization is poorly understood. The aim of this study was to quantify ...

Abstract: We propose a new method for QT interval measurement which first detects the morphology of the T-wave and then finds the T-end according to the detected morphology. The proposed method has ...

Introduction and objectives. Recently we reported that prolongation of the corrected QT (CTc) interval is an independent risk factor in patients with unstable angina and acute ischemic changes. The ...

Abstract: This paper describes a method for accurate and stable measurement of ECG QT intervals. ECG signals from multiple leads are decomposed into orthogonal signals by the algebraic method of ...

In our study, Apple Watch electrocardiographic tracings allowed adequate QT measurements when the smartwatch was worn on the left wrist in 85% of patients. This figure increased to 94% when the ...

Prolongation of the QT interval after exercise can be used to help diagnose long-QT syndrome, especially when the resting QT interval is borderline. The aim of this study was to determine the normal ...

In normal children, any procedure that increases heart rate, such as the tilt test, may shorten the QT interval. The effect of the tilt test on QT interval in children with syncope remains unknown. We ...

Having access to less intrusive QT interval measurement with flexibility around the time and place of the appointment is important 3.1 Psychiatric service user experts explained that it is important ...
