  2. 1. Towards Predictable and Reliable Wireless Communication in Harsh Environments

    Author : Martin Ekström; Maria Lindén; Dag Stranneby; Mälardalens högskola; []
    Keywords : Wireless; Reliable; predictable; Bluetooth; Zigbee; hardware development; measurements; elektronik; Electronics;

    Abstract : Wireless communication in industrial, scientific and medical applications have several benefits. The main benefits when using wireless technologies include ease-of-deployment, the simplicity to introduce new units into the network and mobility. READ MORE

  4. 2. Detection and Classification in Electrocardiac Signals

    Author : Magnus Åström; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; morphology classification; QRS detection; ischemia; body position changes; electrogram; ECG; electrocardiogram; clustering; classification; Detection; sensing;

    Abstract : Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. READ MORE

  5. 3. ST analysis of the fetal ECG as an adjunct to fetal heart rate monitoring in labour-a clinical validation

    Author : Håkan Noren; Göteborgs universitet; []
    Keywords : fetal ECG; ST analysis; electronic fetal monitoring; cardiotocography; fetal blood sampling; metabolic acidosis;

    Abstract : The ability to make an accurate assessment of fetal well-being during labour is a great challenge. Animal and human studies have shown that fetal hypoxemia during labour can alter the shape of the fetal electrocardiogram (FECG) waveform, notable elevation of the T-wave and depression of the ST segment.

  6. 4. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

    Author : Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. READ MORE

  7. 5. Ventricular repolarization in the human heart : effects of pharmacological and non-pharmacological interventions

    Author : Karolina J. Nowinski; Karolinska Institutet; Karolinska Institutet; []
    Keywords : 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;

    Abstract : 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. READ MORE
