  2. 6. Cardiac memory studies in two human models

    Author : Liliane Wecke; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Cardiac memory; repolarization; pacing; WPW ablation;

    Abstract : 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. READ MORE

  4. 7. Investigation of electrochemical properties and performance of stimulation/sensing electrodes for pacemaker applications

    Author : Anna Norlin; Jinshan Pan; Dieter Scharnweber; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; pacemaker electrode; interfacial property; biomaterial; electrostimulation charge transfer mechanism; electrochemical impedance spectroscopy; transient processes; plasma electrolysis anodisation; porous niobium oxide; ruthenium oxide; nano-porous carbon; iridium oxide; titanium nitride; platinum; surface roughness; porous electrode; pacing impedance; electrode polarisation; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Abstract : People suffering from certain types of arrhythmia may benefit from the implantation of a cardiac pacemaker. Pacemakers artificially stimulate the heart by applying short electrical pulses to the cardiac tissue to restore and maintain a steady heart rhythm. By adjusting the pulse delivery rate the heart is stimulated to beat at desired pace. READ MORE

  5. 8. Surgical Ablation of Atrial Fibrillation with Cryo and Radiofrequency Concomitant to Mitral Valve Surgery : Clinical, Biochemical and Echocardiography Outcomes

    Author : Gabriella Boano; Farkas Vánky; Meriam Åström Aneq; Lena Jideus; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; Mitral valve surgery; Surgical ablation; Cox-Maze IV; Left atrium remodelling; 3D echocardiography;

    Abstract : Atrial fibrillation (AF) is the most common arrhythmia seen in clinical practice. In cardiac surgery, the negative influence of AF on short- and long-term outcomes has made concomitant ablation procedures more common. READ MORE

  6. 9. Characterisation of Atrial Electrophysiology with respect to Atrial Fibrillation - A Non-Invasive Approach

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

    Abstract : 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. READ MORE

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

    Author : Davood Javidgonbadi; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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). READ MORE
