  1. 1. Cardiac memory studies in two human models

    Författare :Liliane Wecke; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cardiac memory; repolarization; pacing; WPW ablation;

    Sammanfattning : Background: Cardiac memory is a form of electrical remodeling of the ventricles, where the T vector follows ("remembers') a previously altered QRS vector. On the electrocardiogram (ECG), it presents as T-wave inversions. LÄS MER

  3. 2. Ventricular repolarization in the human heart : effects of pharmacological and non-pharmacological interventions

    Författare :Karolina J. Nowinski; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :QT interval; QT dispersion; PTCA; ischemia; T vector loop; AV junctional RF ablation; arrhythmia; sex hormones; hormone replacement therapy; cardiac memory ECG; signal-averaged ECG;

    Sammanfattning : Ventricular arrhythmias is the main cause of sudden cardiac death. A prolonged repolarization might cause such arrhythmias, and an increased understanding about mechanisms is therefore important for their primary and secondary prevention. LÄS MER

  4. 3. Low Power Analog Interface Circuits toward Software Defined Sensors

    Författare :Yajie Qin; Lirong Zheng; Kari Halonen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IoT; software defined sensor; SoC; bio-medical electronics; bio-electric sensor; E-patch; wearable sensor; wearable healthcare system; pervasive healthcare; CMOS; ADC; digital calibration; analog front-end; folded reference.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Internet of Things is expanding to the areas such as healthcare, home management, industrial, agriculture, and becoming pervasive in our life, resulting in improved efficiency, accuracy and economic benefits. Smart sensors with embedded interfacing integrated circuits (ICs) are important enablers, hence, variety of smart sensors are required. LÄS MER
