Syndrome is a name for a group of symptoms that happen together.
A group of symptoms may collectively indicate a particular condition. If you experience several or more of the symptoms associated with mitral valve prolapse, you may have the Mitral Valve Prolapse Syndrome. The exact cause of the syndrome is still unclear to researchers, but studies indicate that the mitral valve prolapse syndrome is associated with a slight imbalance of the Autonomic Nervous System, called Dysautonomia. The autonomic nervous system is very complex. The sympathetic nervous system tends to increase and accelerate our body functions.
