Filter by:This study assess the accuracy of a blood pressure monitor designed to detect atrial fibrillation. Subjects use the blood pressure monitor on a daily basis for 30 days and compare the readings to an ECG done at the same time.
The purpose of the study is to characterize the performance of the WATCHMAN LAA Closure Device in atrial fibrillation patients for which long term warfarin therapy is contraindicated.
To evaluate whether atrial fibrillation (AF) therapies in Guidant Pulsar Max II or Insignia Plus DR have an effect on the occurance of AF in patients with no prior history of AF
Amiodarone is considered to be the most effective antiarrhythmic drug in the prevention of persistent atrial fibrillation. It can however cause many adverse events, both cardiac and non-cardiac. Long-term maintenance of sinus rhythm after cardioversion is difficult especially because of high recurrence rates during the first month after cardioversion. Duration of atrial fibrillation, type of underlying disease, left ventricular function, left atrial size and age are associated with maintaining sinus rhythm. Early recurrence of atrial fibrillation may be related to a highly arrhythmogenic period due to recovery from electrical remodelling. Late recurrences may be related to other triggers than recovery from electrical remodelling. In this study the investigators want to investigate the effect of amiodarone withdrawal on the occurrence of late relapses of persistent atrial fibrillation. Furthermore, the investigators want to investigate the effect of amiodarone withdrawal on the occurrence of amiodarone related adverse events as well as adverse events related to atrial fibrillation or underlying heart disease. The investigators also want to investigate which patients characteristics are and potential triggers have a prognostic value in the occurence of late relapses after amiodarone withdrawal.
Individuals taking warfarin often need frequent dose changes as the international normalized ratio (INR) gets too high or too low which could result in a higher risk of thromboembolism, bleeding and early discontinuation of a highly useful therapy. This study will compare two approaches to warfarin dosing to examine the utility of using genetic information for warfarin dosing.
The purpose of this registry is to produce a prospective, outcome-oriented registry to document the prevalence of AT/AF in the CRM population by using the Advanced AT/AF Diagnostics in select SJM devices.
The purpose of this observational study is to collect data regarding the population of patients implanted with St. Jude Medical ICD.
The primary objective of this study is to compare the incidence of hemorrhagic events in patients treated for non-valvular atrial fibrillation with DU-176b at each dose level versus warfarin potassium (warfarin). The secondary objective includes between-group comparisons with regard to incidence of thromboembolic events, pharmacodynamic parameters, and biomarkers for the efficacy evaluation, as well as incidence of adverse events and adverse reaction for the safety evaluation.
The primary aim of this proposal is to determine the effectiveness of a decision support tool on improving the process of shared decision-making for treatment on nonvalvular atrial fibrillation (NVAF) compared to receipt of usual care.
The purpose of this study is to examine the overall effectiveness of short-time anti-arrhythmic drug treatment with amiodarone (to control heart rhythm) to prevent short-and long-term atrial fibrillation following an ablation procedure for atrial fibrillation.
