BACKGROUND/AIM The signal-averaging (SA) technique is used to record high-resolution electrocardiograms (HRECGs) showing cardiac micropotentials. We aimed to develop a non-invasive signal-averaging-based portable bedside device to determine His-ventricle interval. PATIENTS AND METHODS After amplifying the HRECG recordings, signal duration and voltage can be measured up to four decimal precisi...

We read with interest the article by Murk et al. (4). The authors conclude that a simple overnight preenrichment step improves the detection of extended-spectrum-beta-lactamase (ESBL)-positive strains and permits earlier recognition and isolation of patients who carry these strains. We would like to address some concerns we have about the validity of these data. First, it is of major importance...

The accuracy (sensitivity and specificity) of a new screening test can be compared with that of a standard test by applying both tests to a group of subjects in which disease status can be determined by a gold standard (GS) test. However, it is not always feasible to administer a GS test to all study subjects. For example, a study is planned to determine whether a new screening test for cervica...

Introduction: Semi-automatic neuropsychological testing has gained a position both in clinical use and in research. Comparison studies with traditional neuropsychological tests are sparse and the role of such semi-automated testing is debated. To integrate semi-automated neuropsychological testing in the established clinical setting the tests must be validated in the patient groups addressed. T...
