Atrial fibrillation is one of the most common rhythms you'll encounter in a hospitalized patient. With this rhythm, the atria are contracting rapidly and at an irregular rate (very erratic). The atria are basically quivering, which increases the risk of a blood clot developing, which could lead to a stroke.

On an ECG strip, you'll notice that P waves are not present before the QRS complex. Instead, the P waves are replaced with irregular fibrillatory waves (also called F waves or fibrillary waves).

QRS complexes are present and measure less than 0.12 seconds, and the ventricular rate is irregular.

Many things can cause atrial fibrillation, such as heart problems (mitral valve disease, CAD, myocardial infarction, pericarditis, sleep apnea, and more).

Treatment can vary depending on whether the patient is stable or unstable, as well as the type of atrial fibrillation (controlled or uncontrolled). Sometimes an ablation is used in addition to other treatments such as synchronized cardioversion and anticoagulant medications.
