Get atrial fibrillation (AFib) materials for healthcare professionals and patients.The EKG rhythm will appear regular, but atrial and ventricular rhythms are independent. Heart rate is characterized by atrial rate usually normal but faster than the ventricular rate. The P wave will have normal shape and size but may appear within QRS complexes. The PR interval is absent: the atria and ventricles beat independently.Electrocardiogram (ECG) An electrocardiogram (ECG) is a graphic representation of the electrical activity of the heart plotted against time. Electrocardiograms are simple, inexpensive, noninvasive, and readily obtained. Adhesive electrodes are affixed to the skin surface allowing measurement of cardiac impulses from many angles.EKGmon is a telemetry monitoring and quiz platform.
