Aims The implantable loop recorder (ILR) continuously monitors the heart’s electric activity by means of a subcutaneous bipolar electrogram (Elg). Currently, the relationship between the Elg and the surface electrocardiogram (ECG) has been poorly documented. This model-based study aimed at investigating the differences between the bipolar surface and subcutaneous signals, as well as the effect ...

The aim of this study was to determine whether subtle changes in the energy-to-N ratio of medium-concentrate diets alters hepatic export protein synthesis and the partition of protein metabolism in the whole body of growing rams. Rams (n = 6; 41.5 +/- 2.6 kg of BW) were fitted with catheters for measurement of Leu and Phe tracer kinetics across the portal drained-viscera (PDV) and liver. Rams w...

AIMS Implantable loop recorders (ILRs) with specific atrial fibrillation (AF) detection algorithms (ILR-AF) have been developed for continuous AF monitoring. We sought to analyse the clinical value of a new AF monitoring device and to compare it to serial 7-day Holter. METHODS AND RESULTS Sixty-four consecutive patients suffering from paroxysmal AF were included in this prospective analysis a...

AIM To evaluate the incidence, diagnostic yield and safety of implantable loop recorders (ILRs) in patients with or without structural heart disease (SHD). METHODS AND RESULTS Two-hospitals, observational, prospective study in consecutive patients with unexplained syncope who underwent an ILR implantation. Between November 1997 and December 2002, a total of 2052 patients with syncope were eva...

INTRODUCTION Placement of the Reveal implantable loop recorder (ILR; Medtronic Inc., Minneapolis, MN, USA) has previously involved preoperative cutaneous mapping to determine the optimal location. We describe an anatomic-based approach to ILR placement that does not require cutaneous mapping. METHOD A total of 63 patients (40 women, 23 men, mean age 38 ± 15 years) were included in the study. ...

OBJECTIVE To evaluate efficacy of the recently introduced implantable loop recorder (ILR) in establishing symptom-rhythm correlation in young patients with syncope, near syncope, palpitations, and acute life-threatening events (ALTEs). METHODS A retrospective study was conducted with patients with ILR from 3 pediatric centers. Inclusion criteria were age <or=25 years and a minimum follow-up o...

BACKGROUND To estimate the short- and long-term financial impact of early referral for implantable loop recorder diagnostic (ILR) versus conventional diagnostic pathway (CDP) in the management of unexplained syncope (US) in the Portuguese National Health Service (PNHS). METHODS A Markov model was developed to estimate the expected number of hospital admissions due to US and its respective fin...

Assessment of the aetiology of syncope in children can be challenging. In the majority of cases, the cause can be determined from a careful personal and family history, and physical examination. Additional testing such as an ECG, stress test, Holter monitoring and echocardiogram are useful in helping to ferret out the aetiology of syncope. Tilt table testing is also occasionally considered in p...

As a consequence of improved S/N, spectral resolution and wavelength coverage various authors have introduced, without strong justification, new emitting regions to account for various emission line profile differences in AGN. The so-called CIVλ1549 intermediate line region (ILR) appears to be especially ill-defined. We present observational evidence that suggests the ILR is statistically indis...
