1. 1. Assessing Symptom Burden and Health-Related Quality of Life in patients living with arrhythmia and ASTA : Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmia

   Författare :Ulla Walfridsson; Anna Strömberg; Kristofer Årestedt; Nils Edvardsson; Linköpings universitet; []
   Nyckelord :Arrhythmias; Symptom burden; Health-Related Quality of Life; Patient-reported outcomes; Validation; Disease-specific questionnaire;

   Sammanfattning : Background: Health-Related Quality of Life (HRQOL) can be negatively affected in patients living with arrhythmias and many patients experience a pronounced symptom burden. The arrhythmia can cause both uncertainty and limitations, including interference with work, reluctance to perform and plan for leisure activities and leading to self-imposed restrictions in daily life situations.

3. 2. Common mechanism for teratogenicity of antiepileptic drugs : Drug-induced embryonic arrhythmia and hypoxia-reoxygenation damage

   Författare :Faranak Azarbayjani; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Atiepileptik drugs; embryonic heart; arrhythmia; cleft palate; ROS; antioxidants; Ikr; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Toxicology; toxikologi;

   Sammanfattning : The Antiepilptic drugs (AEDs) phenytoin (PHT), carbamazepine (CBZ), phenobarbital (PB), tri- and dimethadione (TMD and DMD) are known teratogens having a common malformation pattern in human and animal studies. This thesis was designed chiefly to test a hypothesis correlating the teratogenicity of these AEDs to episodes of pharmacologically induced embryonic arrhythmia and hypoxia-reoxygenation damage.

4. 3. On the causes of ventricular arrhythmia, its treatment and outcome

   Författare :Christina M Holmgren; Göteborgs universitet; []
   Nyckelord :Cardiac arrest; ICD; ventricular arrhythmia;

   Sammanfattning : On the causes of ventricular arrhythmia, its treatment and outcome Christina Holmgren Institute of Medicine Sahlgrenska Academy at University of Gothenburg Göteborg, Sweden ABSTRACT Background: Ventricular arrhythmia is the most common aetiology of sudden cardiac death. Death can sometimes be prevented by the implantation of a defibrillator (ICD). LÄS MER

5. 4. Computer-based detection of cardiac arrhythmias : methods and systems

   Författare :Mats-Erik Nygårds; Linköpings universitet; []
   Nyckelord :Arrhythmia; monitoring; feature extraction; QRS delineation; power spectrum; ventricular fibrillation; MEDICINE; MEDICIN;

   Sammanfattning : The aim of this study was to develop methods and systems which could improve the accuracy or arrhythmia monitoring and analysis of long-term ECGs and eliminate or reduce the need for continuous visual ECG screening. The detection of arrhythmias was based on an automatic classification of heart beats, using waveform features obtained from a basis signals representation. LÄS MER

7. 5. Catching broken hearts - Electrocardiography and in-hospital outcome in Takotsubo syndrome versus ST elevation myocardial infarction

   Författare :Rickard Zeijlon; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Takotsubo syndrome; ST elevation myocardial infarction; electrocardiography; arrhythmia; mortality; pathophysiology;

   Sammanfattning : BACKGROUND AND AIMS: Takotsubo syndrome (TS) and acute myocardial infarction (AMI) have similar symptoms, non-invasive test results and complications. Whereas AMI is caused by cardiac ischemia, the pathophysiology of TS is incompletely understood. LÄS MER
