  1. 1. Atrioventricular synchronous pacing in hypertrophic obstructive cardiomyopathy

    Författare :Fredrik Gadler; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HOCM; pacing; LVOTobstruction; quality of life;

    Sammanfattning : The study addresses major issues of cardiac pacing in hypertrophic obstructive cardiomyopathy (HOCM). The influence of ventricular pacing site and atrioventricular (AV)-delay on left ventricular outflow tract (LVOT) gradient. LÄS MER

  3. 2. Factors influencing outcome in patients with obstructive hypertrophic cardiomyopathy - Effects of pharmacotherapy, pacing and surgical myectomy

    Författare :Davood Javidgonbadi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hypertrophic obstructive cardiomyopathy; myectomy; pacing; beta-blocker; survival; sex; re-intervention rate;

    Sammanfattning : Background: Most studies on risk factors for disease-related mortality in hypertrophic cardiomyopathy (HCM) have emanated from specialized tertiary centres which are subject to possible referral bias. About one quarter of HCM-patients have outflow obstruction in the left ventricle, hypertrophic obstructive cardiomyopathy (HOCM). LÄS MER

  4. 3. Cardiac hypertrophy : transcription patterns, hypertrophic progression and extracellular signalling

    Författare :Nina Gennebäck; Stellan Mörner; Anders Waldenström; Urban Hellman; Ali J Marian; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac hypertrophy; HCM; gene expression; OPLS-DA; multivariate dataanalysis; cardiomyocytes; exosomes; microvesicles; Medicine; medicin;

    Sammanfattning : Background: The aim of this thesis was to study transcription patterns and extracellular signalling of the hypertrophic heart to better understand the mechanisms initiating, controlling and maintaining cardiac hypertrophy.Cardiac hypertrophy is a risk factor for cardiovascular morbidity and mortality.

  5. 4. 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

  7. 5. 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
