Final answer:
Atrial fibrillation can lead to complications such as heart murmur and cerebral vascular accident (stroke).
Step-by-step explanation:
Atrial fibrillation can lead to complications such as heart murmur and cerebral vascular accident (stroke). A heart murmur is an abnormal sound heard during a heartbeat, which can be caused by turbulent blood flow due to atrial fibrillation. Cerebral vascular accident, also known as a stroke, can occur as a result of a blood clot originating from the atrium and blocking blood flow to the brain.
