  2. 1. Risk factors for incident heart failure and atrial fibrillation in an elderly population : The role of cardiac conduction and heart rate variability

    Author : Bozena Ostrowska; Carina Blomström Lundqvist; Lars Lind; Mikael Dellborg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; incident heart failure; incident atrial fibrillation; prediction of heart failure; short P-wave duration; heart rate variability.; Cardiology; Kardiologi;

    Abstract : Heart failure (HF) and atrial fibrillation (AF) are epidemic diseases, frequently coexisting, sharing risk factors and conferring poor prognosis. Identification of individuals at high risk of HF and AF may enable early treatment and improve the prognosis. Reliable prediction models for daily clinical practice are lacking. READ MORE

  4. 2. Autonomic cardiac control in long QT syndrome : clinical studies of arrhythmogenic triggers

    Author : Anna Lundström; Annika Rydberg; Urban Wiklund; Håkan Eliasson; Jacob Tfelt-Hansen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT syndrome; pediatrics; exercise; Holter; water immersion; arrhythmia; clinical physiology; ECG; heart rate variability; heart rate response; cardiovascular disease; hjärt- och kärlforskning; kardiologi; Cardiology; pediatrik; Pediatrics;

    Abstract : Background: Long QT syndrome (LQTS) is an inherited cardiac disease characterized by prolonged cardiac repolarization and an increased risk for life-threatening arrhythmias. These arrhythmias are typically triggered by adrenergic stimuli, such as physical activity and intense emotions, implicating that the sympathetic part of the autonomic nervous system (ANS) is involved in arrhythmogenesis.

  5. 3. Ischaemic heart disease - risk assessment, diagnosis, and secondary preventive treatment in primary care : with special reference to the relevance of exercise ECG

    Author : Gunnar Nilsson; Eva Samuelsson; Thomas Mooe; Per Wändell; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise ECG; Ischaemic heart disease; Myocardial infarction; Prehospital delay; Primary care; Prognosis; Referral; Statin; Secondary prevention; Arbets-EKG; hjärtinfarkt; ischemisk hjärtsjukdom; sekundärprevention; Family Medicine; allmänmedicin;

    Abstract : Background: Ischaemic heart disease is a diagnostic and therapeutic challenge to most general practitioners. We sought to identify diagnostic characteristics and prognoses of patients in primary care that received exercise electrocardiography (ECG). We compared the ECG test results with respect to probability of subsequent cardiologist referrals. READ MORE

  6. 4. Pathophysiology of intrauterine asphyxia

    Author : Anna-Karin Welin; Göteborgs universitet; []
    Keywords : asphyxia; ECG; endotoxemia; fetal sheep; inflammation; melatonin; periventricular leukomalacia; preterm;

    Abstract : Background: The premature infant is at increased risk of cerebral white matter damage, oftenreferred to as periventricular leucomalacia, PVL, which is associated with later developmentof cerebral palsy and cognitive impairment. The etiology of PVL remains unclear, but ischemia-reperfusion followed by generation of free radicals and intrauterine infections havebeen suggested to play an important role. READ MORE

  7. 5. Detection of myocardial ischemia : clinical and experimental studies with focus on vectorcardiography, heart rate and perioperative conditions

    Author : Sören Häggmark; Ulf Näslund; Michael F Haney; Mårten Rosenqvist; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; myocardial ischemia; pacing; vectorcardiography; electrocardiography; heart rate; myocardial lactate; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; kardiologi; Cardiology;

    Abstract : Introduction. Multiple clinical methods for detecting myocardial ischemia are utilised in the hospital setting each day, but there is uncertainty about their diagnostic accuracy. READ MORE
