95 Fluoroscopy times in electrophysiology and device procedures: impact of single frame location fluoroscopy
Background: The current European Heart Rhythm Survey has shown that occupational X-ray hazard in electrophysiology (EP) and device procedures is notable and has not changed in the last few years. Consensus guidelines recommend that current fluoroscopy practice should be revised. We investigated the impact of non-gridded, single frame location fluoroscopy on screening times for EP and device procedures. (Source: Europace)

92 Pan London ‘know your pulse’ awareness campaign during world heart rhythm week 2017
Introduction: Atrial fibrillation (AF) is the most common cardiac arrhythmia and is responsible for 1 in 5 strokes. AF is frequently asymptomatic and it is estimated that there are 68,000 people in London living with the condition undetected. A simple check of the regularity of an individual ’s pulse rhythm can help to improve detection rates and ensure people are initiated on an appropriate treatment to reduce their risk of AF-related stroke.

9 Implementation of opportunistic screening at Pre-Assessment Clinics for upgrade/downgrade of cardiac devices
Background: It has long been acknowledged that conventional right ventricular pacing can result in pacing-induced left ventricular deterioration (PiLVD). Bi-ventricular pacing (BiVP) has long been established as a beneficialde Novo treatment for LV dyssynchrony/dysfunction in terms of quality-of-life, functional status and cardiac efficiency, but only recently proved similarly beneficial for those with PiLVD. Current guidelines by the European Society of Cardiology (2013) now recommend patients with existing cardiac devices should be upgraded to BiVP devices if they meet the criteria required for new device implantation.

8 Pre-existing right ventricular paced heart failure patients upgraded to cardiac resynchronisation therapy devices: a retrospective assessment of the functional and clinical benefits
Introduction: Heart failure (HF) affects 1-2% of the adult population in the Western world, rising to more than 10% among those aged 70 years and older. In 15-30% of this population, intraventricular dyssynchrony exists. A series of large randomised trials demonstrated cardiac resynchronisation therapy (CRT) as a highly effective therapeutic option for moderate-to-severe HF patients with an ejection fraction less than 35% and a QRS width greater than 120ms. However, chronic right ventricular (RV) pacing is known to increase the risk of developing HF. This sub-group of HF patients were excluded from these trials; and resear...

The subcutaneous ICD (S-ICD) has been developed to reduce the risk of lead complications in patients requiring prophylactic ICDs. It has also been recommended for patients with adult congenital heart disease (ACHD) who often have complex cardiac anatomy, preventing the implantation of a transvenous system. such as patients who have undergone Fontan palliation, who subsequently have a ...

91 Trans-coronary pacing to assess myocardial viability prior to percutaneous coronary intervention
Background: The assessment of myocardial viability is crucial before percutaneous coronary intervention (PCI) is carried out to ensure that the patient will gain benefit from the procedure. There are a range of imaging investigations which can used to assess myocardial viability but these are often time- and resource-intensive tests which can delay revascularisation. Trans-coronary pacing (TCP) is a technique which can be performed at the time of intervention and has previously been used to pace myocardium.  However, it may also provide information on myocardial viability.

87 Clinical evaluation of the ‘pulse smart rhythm analyst’: a novel software algorithm and pulse oximeter combination for mass screening of atrial fibrillation
Introduction: Atrial fibrillation (AF) is the most common cardiac arrhythmia, with a prevalence of 1-2% in the general population. 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. However, screening programmes to detect asymptomatic AF have not been undertaken; in part due to the prohibitive logistics and cost effectiveness of 12-lead ECGs and clinicians able to interpret them. We designed and evaluated a practical and scalable technology to address this. (Source: Europace)

86 Incorrect coding of atrial fibrillation leads to under-treatment with anticoagulation in pacing clinics
Background: Timely treatment of Atrial Fibrillation (AF) is necessary to ensure that patients reduce their risk of a thrombo-embolic event. AF is both under-recognised and under-treated with anticoagulation. Patients with established AF who are inappropriately coded are at risk of sub-optimal management. Pacemakers (PPMs) detect all episodes of paroxysmal AF, but are not routinely formally used for this purpose. (Source: Europace)

85 A new mapping technique for atrial fibrillation shows frequent focal and uniform activations
Background: Transient and recurrent uniform wavefronts have been observed during persistent atrial fibrillation (psAF), and might be explained by a focal source at their origin. Mapping has largely involved the use of epicardial multielectrode arrays during invasive cardiac surgery. At present there is inadequate mapping technology to study this during an endocardial procedure using conventional equipment. To further understand the underlying mechanism perpetuating psAF, we have developed an alternative method for analysing activation sequences allowing us to build a composite map of directions of uniform activation.
