1. 1. Lung Emphysema & Cardiac Function

   Författare :Kirsten Jörgensen; Göteborgs universitet; []
   Nyckelord :emphysema; hemodynamics; ventricular end-diastolic volumes; lung volume reduction; ventricular function; transoesophageal echocardiography; magnetic resonance imaging; diastole; simendan; hypertrophy;

   Sammanfattning : Patients with severe lung emphysema have poor quality of life because of impaired lung function and reduced exercise tolerance. Concomitant heart disease in severe emphysema is well recognised. The prevailing view is that mainly the right side of the heart is involved, while the issue of left ventricular (LV) involvement is less studied. LÄS MER

3. 2. Transoesophageal and transthoracic recordings of mitral annulus motion

   Författare :Bo Nilsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Left ventricular function; echocardiography; M-mode; tissue Doppler; mitral annulus systolic and diastolic velocities;

   Sammanfattning : Maximal systolic and diastolic velocities recorded from four sites of the mitral annulus motion (MAM) reflect left ventricular (LV) performance. This thesis focus on factors influencing M-mode derived velocities in healthy children and adults and reference values are proposed. LÄS MER

4. 3. The oesophageal route in clinical electrocardiology

   Författare :Steen Pehrson; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; oesophageal electrocardiogram; cardiac pacing; Transoesophageal stimulation; arrhythmias; non-invasive electrophysiology; atrial fibrillation; supraventricular tachycardia; Kardiovaskulära systemet;

   Sammanfattning : The subject of this thesis is the clinical use of the oesophageal electrode in electrocardiology. The three areas covered are oesophageal electro- cardiography, the biophysics of transoesophageal atrial stimulation (TAS) and the clinical utility of TAS. The literature is reviewed with respect to these areas. LÄS MER

5. 4. Aortic coarctation : Physiological and model studies

   Författare :Jan Engvall; Dag Teien; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : In 22 patients, referred for the assessment of significant native- or re-coarctation, the systolic cuff blood pressure difference between arm and ankle at rest and after three different subrnaximal exercise tests and one maximal test was compared with invasive blood pressure. Reference values of cuff blood pressure were obtained from 19 healthy adult volunteers. LÄS MER

7. 5. Characterisation of Atrial Electrophysiology with respect to Atrial Fibrillation - A Non-Invasive Approach

   Författare :Fredrik Holmqvist; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Atrial fibrillation; Human; Conduction; Signal; Spectral analysis; P wave morphology; Atrial remodelling; Cardiovascular system; Kardiovaskulära systemet;

   Sammanfattning : Atrial fibrillation (AF) is the most common form of cardiac arrhythmia encountered in clinical practice, accounting. Recent findings highlight the need for better characterisation of the arrhythmia in each patient, in order to improve patient treatment. LÄS MER
