67 year old male patient monitored during esophagogastrectomy. Patient has a history of smoking and aspiration.
Rhythm analysis indicates normal sinus rhythm (NSR) which converts into atrial fibrillation (AFib) with PVCs.
This encounter shows a normal sinus rhythm converting into atrial fibrillation. This is an important conversion to spot, as atrial fibrillation can cause complications such as blood clots. Treatment teams must be aware of a patient converting into AFib! Notice the transition from a regular rhythm to irregular, and the disappearance of P waves. Also present are small 'flutter waves' typical of AFib.
