78 year old male patient with cerebral hemorrhage and coronary artery disease monitored.
Rhythm analysis indicates atrial fibrillation with premature ventricular contractions (PVCs).
This encounter shows an irregular rhythm with no P waves present. Small 'flutter waves' can be seen upon magnification. 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.
