Atrial Fibrillation and Flutter Outcomes & Risk Determination inclusion and exclusion criteria

Inclusion criteria

ED patients 18 years and older Have a documented diagnosis of AF or atrial flutter on an ED electrocardiogram or rhythm strip Present with signs (tachycardia, dyspnea) or symptoms (palpitations, chest pain, shortness of breath, weakness, lightheadedness, pre-syncope, or syncope) consistent with primary symptomatic AF. We will also include patients whose primary complaint is not directly related to their AF diagnosis (e.g. evaluation for febrile illness, gastrointestinal complaint, injury) BUT have a secondary complaint consistent with symptomatic AF that requires ED evaluation. These situations will include the following: new AF diagnosis, AF associated with inadequate rate control (defined as resting heart rate greater than 100 bpm), AF associated with heart failure symptoms, AF in the setting of CVA or TIA, AF associated with other thromboembolic complications. ED patients who present with complaints unrelated to their AF (e.g. sprained ankle, pharyngitis) and have adequately rate (<100 bpm at rest) or rhythm controlled-AF will not be eligible for inclusion on that ED visit. Provided informed consent and signed Health Insurance Portability and Accountability Act waiver for collection of private health data.

Exclusion criteria

Patients unwilling or unable to give informed consent Previously enrolled in this study Seek ED treatment for a primary or secondary complaint not related to AF or atrial flutter. There will be no exclusion by race, gender or ethnic characteristics.

AF, atrial fibrillation; ED, emergency department.
