Atrial Fibrillation
Conditions
Brief summary
Researchers are trying to determine whether arterial stiffness detected by ultrasound can predict outcomes in the development and recurrence of atrial fibrillation.
Interventions
DIAGNOSTIC_TESTCarotid Ultrasound
Uses sound waves to examine the blood flow through the carotid arteries and to determine the elastic properties or stiffness of the artery.

ALL
Age
18 Years to 95 Years

Exclusion criteria
* Unable to provide informed consent. * Patients with intramural thrombus or other conditions that preclude the performance of electrical cardioversion. * Patients with prior carotid stents.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Recurrence of Atrial Fibrillation following cardioversion | 6 months | We will follow up by phone or look through medical records to record the number of subjects that have had a recurrence of Atrial Fibrillation. We are also looking if we can correlate the recurrence with arterial stiffness. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Occurrence of heart failure | 6 months | Number of subjects to have heart failure following cardioversion |
| Occurrence of stroke | 6 months | Number of subjects to have a stroke following cardioversion |
| Occurrence of hospitalization | 6 months | Number of subjects that have been hospitalized following cardioversion |
