Atrial fibrillation (AF) and heart failure (HF) are morbid, costly, and incompletely understood diseases that have reached epidemic proportions worldwide. A dose-dependent relationship exists between premature atrial and ventricular contractions (PACs and PVCs) and development of AF and HF, respectively. Identifying and understanding the mechanisms of additional modifiable risk factors for ectopy has the potential to markedly reduce the healthcare burden of these diseases. In considering how to modify the prevalence of these ectopic beats, the investigators believe common exposures in daily life are prime candidates. Current guidelines suggest that caffeine may be an important trigger for frequent ectopy, although large population-based studies have not demonstrated an association between caffeine consumption and development of clinically significant arrhythmias. No study has employed an actual randomization intervention to assess the effects of caffeine on cardiac ectopy. Utilizing the Eureka platform, the investigators plan to utilize the N-of-1 strategy to rigorously investigate the real-time effect of caffeine intake on ectopy.
This study is a single-arm, prospective, multi-center study to assess clinical performance of the SHERLOCK 3CG™ Diamond Tip Confirmation System (TCS) with MODUS II software for confirming correct tip position of peripherally inserted central catheters (PICCs) in adult subjects with altered cardiac rhythm.
This study is intended to compare the feasibility, safety and efficacy of a zero-fluoroscopic approach with conventional fluoroscopic approach as performing catheter ablation of right atrial arrhythmias.
The primary objective of this research is to determine whether oral magnesium supplementation in healthy, community-living individuals will be associated with reductions in the burden of arrhythmias in the upper chambers of the heart (supraventricular arrhythmias).
The purpose of this study is to estimate the clinical relevance of monitoring patients with acute ischemic stroke with 48 hours' inpatient cardiac telemetry in relation to evaluate the presence of brief runs of premature atrial complexes and new diagnosed atrial fibrillation. Furthermore to evaluate the prognostic significance of brief runs of premature atrial complexes in relation to develop atrial fibrillation, recurrent stroke/transient ischemic attack and death.
This study is designed to prove new methods to enable the automated analysis of esophageal electrocardiography (eECG) signals in long-term measurements as well as the detection of atrial fibrillation. The investigators hypothesis is that eECG signals allow the reliable atrial and ventricular ECG signal distinction and the detection of atrial fibrillation. Therefore 14 patients with arrhythmias and 6 cardiac healthy subjects are asked to take part in this study. On each subject an esophageal ECG and a simultaneous standard surface ECG will be taken for about half an hour. Patient undergoing a cardiac catheter ablation during their current hospitalization will be further asked to allow access to the invasively obtained measurements (i.e. atrial potential map) to further improve the understanding of the eECG signals.

There is accumulating evidence for obstructive sleep apnea (OSA) as an independent risk factor for paroxysmal atrial fibrillation and for high recurrence rates of atrial fibrillation after ablation therapy. We have previously shown that simulated OSA triggers premature atrial beats (PABs) by acute changes in intra-thoracic pressure. Most episodes of atrial fibrillation are initiated by PABs. However, the origin of PABs induced by intra-thoracic pressure swings is unknown. This study investigates the origin of premature atrial beats induced by intra-thoracic pressure changes that simulate obstructive sleep apnea in patients with atrial fibrillation.
The purpose of this study is to improve secondary prevention of ischemic stroke patients by 1. Estimating prevalence and the prognostic significance of frequent premature atrial complexes in ischemic stroke patients in relation to death, recurrent stroke and atrial fibrillation. 2. Characterize ischemic stroke patients by 1. Echocardiographic characteristics 2. Biochemical markers 3. Plaque composition in the carotid arteries - in order to improve risk stratification.
