Filter by:This study is being conducted in order to understand more about how the body responds to a mind/body practice called yoga nidra. Results from this study will be used to inform the design of future studies that investigate the effects of yoga nidra on sleep quality and insomnia. Yoga nidra is a simple guided meditation technique that involves lying still on a mattress while listening to a voice. Participants will follow simple instructions that involve becoming aware of their body and breath, as well as various memories, emotions, and images. This practice is not religious in nature. The investigators do not believe it will conflict with any religious beliefs. The goal of this practice is to help get rid of mental, physical and emotional tensions.
The aim of our project is to develop an epileptic seizure detection algorithm based on the the continuous analysis of the Electrocardiogram
This study will provide further knowledge concerning the use of electrocardiography (ECG) signals for verification of peripherally inserted central catheter (PICC) tip placement. Furthermore, it will be investigating whether use of Intravascular ECG (IVECG) for this verification is just as good as or even better than the current standard method with chest X-ray. This can help promote a method that involves less radiation and increased safety for patients, while at the same time saving resources. If use of ECG signals from the PICC tip is an equally exact method for verification of correct PICC tip placement as chest X-ray verification, the IVECG could replace chest X-ray control.
The objective of the study is to compare electrocardiograms using ambulatory holter monitor with dry electrodes in a harness versus using an ambulatory holter with standard sticky electrodes (Red Dot) on monitored patients within the hospital. Patients will be simultaneously be hooked up to two ambulatory Holter monitors for the period of time to be not less than one hour. One holter will use standard electrodes in a standard electrode distribution. The second holter will use dry electrodes in a derived.
Patients with insulin-dependent diabetes mellitus (DM) and chronic kidney disease (CKD) exhibit an excessive risk for cardiac arrhythmias, in particular sudden cardiac death (SCD). Hypoglycemia is a frequent problem in insulin-treated patients, especially in those with CKD, and various studies have shown that hypoglycemic episodes are strong predictors of cardiovascular mortality in both type 1 and type 2 diabetic patients. Experimental data and small clinical studies link hypoglycemia with ECG changes and SCD, but little is known about the direct association of hypoglycemic events and/or rapid swings in blood glucose with arrhythmias in this high risk population. Ideally, an algorithm should help to identify patients at risk for hypoglycemia-associated arrhythmias and SCD, but hitherto systematic analyses of blood glucose values and 12-channel ECGs are lacking in these patients.
The study is aimed at testing the hypothesis whether atrial fibrillary rate (AFR), as a measure of atrial electrical remodeling assessed from surface ECG, is predictive of sinus rhythm maintenance after electrical cardioversion. Earlier studies performed in a retrospective fashion suggested that high AFR exceeding 350-360 fibrillations per minute is an independent predictor of AF relapse after cardioversion, particularly in patients with duration of AF episode not exceeding 30 days, however this hypothesis has not been tested in a prospective study. CASAF is an observational study that will enroll patients with short duration (< 30 days) AF admitted for electrical cardioversion. Admission ECG will be extracted in a digital format and processed off-line for estimation of AFR. AF relapse will be assessed during 6-weeks long follow-up period during which ECG control will be scheduled at week 1 and 6.
The aim of this study is to investigate the effect of moxifloxacin on the QT interval in order to gain information on the validity of results that will be collected during another clinical study testing riociguat in patients with pulmonary arterial hypertension (PATENT-1 study).
