QT Variability Pre & Post Cardioversion in Patient's With Atrial Fibrillation
The purpose of this study is to learn whether the chemicals in the blood and urine are
different when the heart is atrial fibrillation compared to normal sinus rhythm.
Atrial Fibrillation variably activates the renin-angiotensin-aldosterone system (RAAS),
stimulates the sympathetic nervous system, generates oxidant stress, produces natriuretic
peptides, and increases ventricular rate. These are interrelated responses and the extent
to which these or other pathophysiologic responses determine QT interval during and after
Atrial Fibrillation (AF) is unknown. In this study, the QT variability is related to those
potential markers in patients with AF undergoing elective DC-cardioversion.
Inclusion Criteria:
- At least 21 years of age
- Scheduled to undergo an elective DC-Cardioversion of atrial fibrillation or atrial
flutter at Vanderbilt University Medical Center
Exclusion Criteria:
- Undergoing emergent DC-Cardioversion of atrial fibrillation for hemodynamic
instability
- Undergoing DC-Cardioversion for post-cardiac surgery
- Dual chamber pacemakers
