Conversation: The conversation between human and AI assistant.
[|Human|] The sight in my right eyes was blacking out & I lost the ability to speak for a brief period of time at work, while at theEmergency room the doctor asked how long I had a heart murmur. That was the first time I had heard that mentioned any relationship to the symtoms?
[|AI|]  Heart murmurs are relatively prolonged series of auditory vibrations of variable intensity, quality and frequency. Heart murmurs result from vibrations set up in the bloodstream and the surrounding heart and great vessels (valve or wall) as a result of turbulent blood flow, the formation of eddies, and cavitation (bubble formation as result of sudden decrease in pressure). They are either caused by abnormal valve function or arise from an increased volume, or velocity, of blood flowing through a normal valve. This may occur in a healthy heart.
