Non-invasive remote health monitoring plays a vital role in epidemiological situations such as SARS outbreak (2003), MERS (2015) and the recently ongoing outbreak of COVID-19 because it is extremely r…
BACKGROUND: The electrophysiological mechanisms of spontaneous termination of sustained monomorphic ventricular tachycardia (SMVT), in the postinfarction heart, generally considered secondary to a ree…
PURPOSE: To determine whether measurement of left ventricular (LV) and left atrial (LA) diameters on nongated computed tomography angiography (CTA) can detect left atrial and left ventricular enlargem…
PURPOSE: To avoid motion artifacts, medical imaging devices are often synchronized with the patient's cardiac motion. Today, the ECG is used to determine the heartbeat and therewith trigger the imagin…
In this paper, a fetal electrocardiogram (ECG) monitoring system based on the Android smartphone was proposed. We designed a portable low-power fetal ECG collector, which collected maternal abdominal …
Freezing of gait (FoG) is a common gait impairment among patients with advanced Parkinson's disease. FoG is associated with falls and negatively impacts the patient's quality of life. Wearable systems…
Electron beam tomography (EBT) is a computed tomography technique with unique spatial and temporal resolution. The aim of the study was to establish and evaluate a protocol for the non-invasive visual…
A simultaneous acquisition technique of image and navigator signals (simultaneously acquired navigator, SIMNAV) is proposed for cardiac magnetic resonance imaging (CMRI) in Cartesian coordinates. To s…
BACKGROUND: The Electrocardiogram ECG is one of the most important non-invasive tools for cardiac diseases diagnosis. Taking advantage of the developed telecommunication infrastructure, several approa…
Spectral parameters (SP) of heart rate variability (HRV) and a duration of cardiointervals (RR) in 14 healthy male volunteers at the age of 23-36 years under the influence of acute normobaric hypoxia …
In this paper, an improved empirical mode decomposition (EMD) algorithm for phonocardiogram (PCG) signal de-noising is proposed. Based on PCG signal processing theory, the S1/S2 components can be extr…
With the introduction of long-term ECG by N. Holter more than 25 years ago a more sensitive detection of spontaneous arrhythmias and ST-changes became possible compared with the standard ECG at rest. …
SCH 39166 is a novel and selective dopamine D1 receptor antagonist. It has been reported to have potential antipsychotic properties and reduced extrapyramidal side-effect liabilities (EPS). The curren…
In this paper we report on results from experiments performed on a bi-modal piezoelectric transducer used both as an active ultrasound transceiver and a passive acoustic sensor. The transducer, which …
PURPOSE: To evaluate an improved image acquisition and data-processing strategy for assessing aortic vascular geometry and 3D blood flow at 3T.MATERIALS AND METHODS: In a study with five normal volunt…
BACKGROUND: Rapid identification of a proximal occlusion site of a major coronary artery is of paramount importance in the care of myocardial infarction (MI). It is increasingly recognized that routin…
We have developed the second prototype system of Ubiquitous Integrated Biotelemetry System for Emergency Care(UIBSEC) using a HSDPA(High Speed Downlink Packet Access) modem to be used by emergency res…
This report describes a robust method of Instantaneous Heart Rate (IHR) detection from noisy electrocardiogram (ECG) signals. Generally, the IHR is calculated from the interval of R-waves. Then, the R…
