A Study to Evaluate Potential Myocardial Injury Following Elective Direct Current Cardioversion
Rochester, MN
The purpose of this study is to prospectively determine if direct current cardioversion (DCCV) results in myocardial injury as assessed by changes in high sensitivity cardiac troponin T (hs-cTnT) assay.

A Study to Analyze Arterial Stiffness and Atrial Fibrillation
Rochester, MN
The purpose of this study is to determine arterial stiffness in patients with atrial fibrillation (AF) using acoustic radiation vibrometry, to compare acoustic radiation force (ARF) measurements in patients with AF before and after electrical cardioversion, and to determine whether arterial stiffness predicts recurrence of AF after cardioversion.

A Study to Analyze the Effect of Cardioversion on the Tricuspid and Mitral Valves in Patients with Atrial Fibrillation
Rochester, MN
The purpose of this study is to assess the immediate effect of cardioversion on both the tricuspid and mitral annular dynamics and size in patients with atrial fibrillation, and to compare the annular dynamics and dimensions in both the tricuspid and mitral valves immediately before and after cardioversion in patients with atrial fibrillation using 3D transesophageal echocardiography.

Effect of Wearable Devices on Patient-Reported Outcomes and Clinical Utilization: A Randomized, Controlled Trial
Rochester, MN
The purpose of this study is to help researchers better understand the impact of wearable devices on patient experience and clinical trends following a cardioversion.

Recovery of Left Ventricular Systolic Function and Atrial Fibrillation Recurrence after Restoration of Sinus Rhythm in Patients with Atrial Fibrillation
Rochester, MN
The objectives of this study are: (1) to analyze beat-to-beat variability and the variations of R-R interval to pre-preceding R-R interval (RRp/RRpp) ratio of left ventricular (LV) function by strain imaging (2D speckle tracking echocardiography) in patients with atrial fibrillation (AF) undergoing electrical cardioversion(ECV) or radiofrequency catheter ablation (RFCA) as a predictor of a recovery of LV function and volume after restoration of sinus rhythm , (2) to evaluate left atrial mechanics as a predictor of for AF recurrence after electrical cardioversion (ECV) or radiofrequency catheter ablation (RFCA)
