    “…This paper presents a novel hallway gait extraction system that enables an individual’s spatiotemporal gait parameter extraction at each gait cycle using a single FMCW (Frequency Modulated Continuous Wave) radar. The purpose of the proposed system is to detect changes in gait that may be the signs of changes in mobility, cognition, and frailty, particularly for older adults in retirement homes. …”

    “…Typical ECG changes associated with PE include right axis deviation, right bundle‐branch block, S1Q3T3 pattern, arrhythmia, nonspecific ST‐segment changes, QR pattern in lead V1, Brugada ECG pattern, and T‐wave inversions in the precordial leads. However, his electrocardiogram showed QT‐interval prolongation and simultaneous T‐wave inversions in the inferior and anterior leads. …”
