116 Survey to evaluate awareness and current practice of venous thromboembolism prevention following electrophysiological procedures in the United Kingdom
Introduction: Invasive electrophysiological (EP) studies require the introduction of multiple catheters into the venous system and a period of immobility, both known pro-thrombotic factors. However there is a paucity of data on strategies to prevent venous thromboembolism (VTE) in this population and they are not explicitly covered in NICE guidelines. The aim of this study was to establish the incidence of VTE in those undergoing EP studies and radiofrequency ablation, excluding patients currently taking therapeutic anti-coagulation, and to survey the current practice within UK EP centres for the prevention of VTE.

112 “I don’t know how you can be the decision maker when you don’t understand”: designing a tailored E-health intervention to empower patients living with non-valvular atrial fibrillation
Background: Prevention of thromboembolism is key in individuals with non-valvular atrial fibrillation (NVAF) and nonadherence to oral anticoagulant (OAC) therapy is a frequent causative factor of stroke. Many factors contribute to the complexity of medication nonadherence. Thus, education aimed at changing health behaviors must be tailored to address the unique internal motivations and information needs of those confronted with the daily choice to take a medication to prevent stroke. Delivery of tailored health education and medication reminders may be an effective way to empower individuals with NVAF and in consequence, i...

Background: Dispersion of action potential duration (APD) and repolarization are important factors in the genesis of ventricular arrhythmia, facilitating functional block and reentry. Present substrate mapping of VT not only fails to account for repolarization of the tissue, but assesses scar/voltage in a planar fashion. However, arrhythmias within the heart do not traverse a one-dimensional course. It is highly likely that the wavefront is heterogeneous, taking complex paths involving endocardium, mid-myocardium and epicardium.

99 Temporary pacing optimisation post cardiac surgery. Are we missing a trick?
Introduction: Optimisation of haemodynamic status post cardiac surgery is complex. In the UK, these patients are typically managed by Anaethetists and/or Intesivists. Adjustments in fluid replacement and inotropic support are routine in hypotensive patients, while temporary pacing optimisation is considered less frequently. We hypothesise that for patients with intact atrioventricular (AV) node conduction and appropriate fluid balance, the promotion of intrinsic ventricular conduction may increase blood pressure (BP) and reduce the need for inotropic support.

8 Pre-existing right ventricular paced heart failure patients upgraded to cardiac resynchronisation therapy devices: a retrospective assessment of the functional and clinical benefits

Screening for and anticoagulating patients with asymptomatic AF may prove an additional opportunity to prevent stroke, heart failure and premature death in the general population.
