Latent Semantic Analysis (Landauer & Dumais, 1997) and Hyperspace Analogue to Language (Burgess & Lund, 1997) model meaning as the relations among abstract symbols that are arbitrarily related to what they signify. These symbols are ungrounded in that they are not tied to perceptual experience or action. Because the symbols are ungrounded, they cannot, in(More)
We tested the reliability, acceptability and feasibility of a home-monitoring system for cardiac patients. Each participant was equipped with a mobile phone, an automatic blood pressure device and a digital weight scale. In total, 20 patients (14 patients with chronic heart failure, six patients with hypertension; mean age 50 years, standard deviation [SD](More)
OBJECTIVES Telemonitoring of vital signs is an established option in treatment of patients with chronic heart failure (CHF). In order to allow for early detection of atrial fibrillation (AF) which is highly prevalent in the CHF population telemonitoring programs should include electrocardiogram (ECG) signals. It was therefore the aim to extend our current(More)
According to international standards, cardiac pacemakers have to indicate the status of their batteries upon magnet application by specific stimulation patterns. The purpose of this study has been to assess whether this concept can be used as a basis for automated and manufacturer independent examination of the depletion level of pacemakers in the framework(More)
An algorithm for differentiating ECGs with atrial fibrillation (AF) that will spontaneously terminate within 60 seconds from signals, where it won't, has been developed using the AF termination challenge database from physionet. The algorithm was based on the calculation of the major AF frequency by canceling out the QRS complexes and T waves from the(More)
We report a 37-year-old man with documented aborted sudden death. After resuscitation, the patient showed no structural heart disease but the ECG showed a right bundle-branch block with a descending ST segment elevation in leads V1 and V2. After transient normalization of the ECG, the administration of ajmaline led to spontaneous development of the distinct(More)
