Atrial FibrillationNCT00429884
Studies of Disorders and Mechanisms Related to Atrial Fibrillation Before and After DC-Conversion.
An observational study of Atrial Fibrillation, run by Umeå University at 1 site in Sweden.
Trial summary
The purpose of this study is to investigate if breathing disorders are related to atrial fibrillation and if it is possible to predict recurrence of atrial fibrillation after DC-conversion by changes in heart rate variability and 24 hour ECG. Read more about this study
