AIMS The totally subcutaneous implantable-defibrillator (S-ICD) is a new alternative to the conventional transvenous ICD system to minimize intravascular lead complications. There are limited data describing the long-term performance of the S-ICD. This paper presents the first large international patient population collected as part of the EFFORTLESS S-ICD(More)
AIMS Paced electrogram fractionation analysis (PEFA) has been assessed for the prediction of sudden cardiac death (SCD) in a large-scale, prospective study of patients with hypertrophic cardiomyopathy (HCM). METHODS AND RESULTS We determined the positive predictive value (PPV) of PEFA in relation to other risk factors for SCD and outcomes in 179 patients(More)
OBJECTIVE To assess the quality of echocardiographic images from neonates transmitted over Integrated Service Digital Network 2 (ISDN2) channels. DESIGN Echocardiographic images were viewed live in real time either by a direct video link or by transmission over the commercial network, using one, two, or three ISDN2 channels. The order of the viewing(More)
OBJECTIVE To examine autonomic function as assessed by heart rate variability in patients 10 or more years after repair of tetralogy of Fallot, and to relate this to cardiac structure, function, and electrocardiographic indices. METHODS Heart rate variability was measured by standard time domain techniques on a 24 hour Holter ECG in 28 patients, aged 12(More)
COMPASS In an era of heightened competition for scarce research positions and funding, the mantra of modern academia—''publish or perish''—continues to intensify [1]. Scientists are under increasing pressure to produce as many publications as possible in ''high-impact'' journals to raise their profile among peers and influence their discipline. Yet, in(More)
AIM To assess initial experience of cardiac catheterisation in children by the transhepatic approach where conventional venous access is impossible. PATIENTS AND METHODS Percutaneous transhepatic cardiac catheterisation was performed on six occasions in five children (three male) aged 4 to 36 months (mean 17 months). All children had documented femoral(More)
