78 year old female patient monitored during superior mesenteric embolectomy. Patient has a history of mitral stenosis.
Rhythm analysis indicates atrial fibrillation with clear 'flutter waves'.
This encounter shows an irregular rhythm with no P waves present. Clear 'flutter waves' can be seen. These signs are indicative of atrial fibrillation or AFib. The atria quiver rapidly, with most electrical impulses being blocked before reaching the ventricles. This leads to an extremely high and unproductive atrial rate, but throttled ventricular rate. Atrial fibrillation can cause an increased risk of blood clots.
