Filter by:Heart failure patients represent a group of individuals at higher risk for cardiac arrhythmias. There is a perception that caffeine consumption may represent an increase in this risk. Although the medical staff and health professionals suggest a reduction in the intake of this substance to patients considered at risk, there is no scientific proof for this recommendation. Some animal studies suggest a possible association between arrhythmias and caffeine use with higher doses, but this finding did not appear in human studies. In particular, little is known about the association between caffeine consumption and arrhythmias in patients with heart failure, especially at higher doses of consumption. More specific and safe guidelines on caffeine consumption are needed.
To evaluate the efficacy of dexmedetomidine for the prevention of catheter-related bladder discomfort
The bile acids has been demonstrated to cause arrhythmia and abnormal calcium dynamics in cultured neonatal rat cardiomyocytes. Bile acids may alter maternal cardiomyocyte function like fetus.Increased P-wave duration and P-wave dispersion have been reported in various clinical settings. The investigators hypothesized that PWD and p wave duration may affect in pregnancy with ICP.
The purpose of this study is to assess efficacy of prolonged Full Disclosure electrocardiogram (ECG) monitoring and signal analysis using advanced telemetric technology to diagnose arrhythmia in comparison with standard diagnostic procedure.

Exercise therapy has proven to be an effective additive therapy in patients with cardiovascular diseases. The prognostic value of physical activity is well established in patients with congestive heart failure. Therefore the investigators assumed that the population of patients with implantable cardioverter-defibrillators (ICD) with impaired left ventricular function may also benefit from a cardiovascular training in terms of improved quality of life and reduction of ventricular arrhythmia. The data on feasibility, risk and therapeutic effects of exercise training are very limited or not available. This prospective randomized study examines the feasibility and benefits of exercise therapy in patients with ICD and congestive heart failure.
The overall hypothesis of this study is that subtle interactions between structural (substrate) and functional (trigger) abnormalities of the heart, some of which are genetically-determined, can be used to identify patients at high risk of sudden cardiac death (SCD). Such information may be used to better define patients most likely to benefit from replacement of an internal defibrillator (ICD). The prospective, observational study to enroll, categorize and follow patients who receive an ICD pulse generator replacement for primary prevention of SCD (PROSe-ICD) was established to : 1. to gain a better understanding of the biological mechanisms that predispose to SCD 2. to develop readily determined clinical, electrocardiographic, genetic and blood protein markers identify patients with an increased risk of dying suddenly
The purpose of the study is to collect EEG's as close to the cardiac arrest as possible using a standard hospital EEG machine and an investigational EEG device to help determine the neurological status of the cardiac arrest patient and to help decide on possible treatment and chance of recovery. The investigational EEG machine will be simple to operate as well as easy to interpret for the clinician and the nurses. It is not to replace the electrophysiologist interpretation but to determine ealy on if further evaluation and treatment can help the patient.
This study is being conducted to see if magnesium can reduce the number of shocks patients with ICDs experience and to see if magnesium supplementation improves patients quality of life.
The main purpose of the Product Performance Report (formerly referred to as System Longevity Study) is to evaluate long-term performance of Medtronic market-released cardiac rhythm products by analyzing product survival probabilities.
