Wearable sensor systems (WSS) have garnered substantial attention as they showcase their
versatility not only in the development of automated healthcare systems and shaping smart …

The present article proposes an ECG simulator that advances modeling of arrhythmias and
noise by introducing time-varying signal characteristics. The simulator is built around a …

Background: Slow adaptation of the QT interval to abrupt changes in heart rate (HR) can
enhance ventricular heterogeneity and has been suggested as a marker of arrhythmic risk …

Atrial fibrillation (AF) is a life threatening cardiac abnormality having high prevalence and
risk with increased rate of stroke and systemic embolism, if oral anticoagulation is not …

Background: Slower adaptation of the QT interval to sudden changes in heart rate has been
identified as a risk marker of ventricular arrhythmia. The gradual changes observed in …

Cardiovascular diseases are best diagnosed using multiple modalities that assess both the
heart's electrical and mechanical functions. While effective, imaging techniques like …

Atrial Fibrillation (AF) is defined as a heart beating irregularly. It may increase the risk of
stroke and sometimes results in heart failure. Lately, the number of patients with AF …

The precise detection of falls is essential for promptly providing first aid to individuals who
are at risk of accidental injury. Presently, the predominant approach for detecting falls is …

Slowed adaptation of the QT interval to sudden abrupt heart rate (HR) changes has been
identified as a marker of ventricular arrhythmic risk. However, abrupt HR changes are …

The aim of this study is to investigate the relationship between the RR and QT series through
the bivariate phase-rectified signal averaging (BPRSA) computed during RR decelerations …
