2. 1. Long QT syndrome in Sweden : founder effects and associated cardiac phenotypes

   Author : Annika Winbo; Annika Rydberg; Eric Schulze-Bahr; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT Syndrome; Jervell and Lange-Nielsen Syndrome; inherited arrhythmia; founder effects; clinical genetics; haplotype analysis; mutation age; founder mutation; clinical phenotype; life-threatening cardiac events; mutation-specific; KCNQ1 gene; modifier genes; sequence variants; risk stratification; risk factor; gender; pediatrik; Pediatrics;

   Abstract : Background: We aimed to increase the knowledge regarding the familial arrhythmogenic disorder Long QT Syndrome (LQTS) and its recessive variant Jervell and Lange-Nielsen Syndrome (JLNS) in Sweden, including prevalences and clinical phenotypes. A specific focus was directed towards two KCNQ1 mutations –p.Y111C and p. READ MORE

4. 2. Heart rate variability and pacemaker treatment in children with Fontan circulation

   Author : Jenny Alenius Dahlqvist; Annika Rydberg; Urban Wiklund; Jaana Pihkala; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital heart disease; Fontan circulation; heart rate variability; pacemaker; sinus node dysfunction; pediatrik; Pediatrics; kardiologi; Cardiology;

   Abstract : Background: Fontan surgery is performed in children with univentricular heart defects. Arrhythmias are frequent complications, occasionally requiring pacemaker treatment. Previous data regarding indications and risk factors for pacemaker treatment in Fontan patients is limited and conflicting. READ MORE

5. 3. Psychosocial aspects of living with congenital heart disease : child, family, and professional perspectives

   Author : Anna-Lena Birkeland; Annika Rydberg; Bruno Hägglöf; Lennart Köhler; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breaking bad news; children adolescents; congenital heart disease; communication; content analyse; coping; counselling; interprofessional team; medical education; patient relationships; paediatric cardiology; professional role; psychosocial inventory method; qualitative method; quantitative method stress; teamwork;

   Abstract : Background: The vast majority of infants born with congenital heart disease (CHD) reach adulthood because of the developments in cardiology in recent decades. This thesis aims to describe the psychosocial situation of child/adolescent cardiac patients and their families, investigate the situation faced by parents and siblings initially and over time, investigate the approaches paediatric cardiologists use in encountering the family, and describe the teamwork occurring in paediatric cardiology teams (PCTs) in Sweden.

6. 4. Myocardial electromechanical function in long QT syndrome

   Author : Dafni Charisopoulou; Michael Y. Henein; Annika Rydberg; Anders Jonzon; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT syndrome; stress-echocardiography; left ventricular filling; mechanical dispersion; diastolic myocardial function; exercise; arrhythmia; electromechanical window; speckle-tracking echocardiography; myocardial relaxation sequence.; kardiologi; Cardiology; cardiovascular disease; hjärt- och kärlforskning;

   Abstract : AIM: The aim of this thesis is to assess, in LQTS and according to genotype, the myocardial electromechanical (EM) function response to exercise, its relation to symptoms and its response to b-blocker therapy. To achieve this aim, we conducted 4 studies with the following specific objectives: i. READ MORE

7. 5. Long QT syndrome : studies of diagnostic methods

   Author : Ulla-Britt Diamant; Steen M Jensen; Annika Rydberg; Thomas Gilljam; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kardiologi; Cardiology;

   Abstract : Background: The Long QT Syndrome (LQTS) is a hereditary heart disease with risk of malignant ventricular arrhythmia and sudden cardiac death. Despite our increased knowledge about genotype and phenotype correlation we still rely on the 12-lead ECG for assessment of the QT interval and the T-wave morphology for diagnosis and risk stratification.
