(CDISC) AFib Irregular heart rhythm, usually associated with a rapid rate, that is caused by abnormal electrical activity within the atrial. Atrial fibrillation MedDRA Cellosaurus C4015486 A disorder characterized by a dysrhythmia without discernible P waves and an irregular ventricular response due to multiple reentry circuits. The rhythm disturbance originates above the ventricles. Atrial Fibrillation Patient Code (Appendix B) IMDRF:E060102 Atrial Fibrillation CPTAC FDA An irregular heart rhythm, usually associated with a rapid rate, that is caused by abnormal electrical activity within the atria.
