What are the symptoms of mitral valve prolapse?
Most people with MVP experience no symptoms. Some may experience difficulty breathing during exertion or when lying down, tremor, fatigue, lightheadedness, dizziness, and fainting. Some develop dull chest pain, palpitations (awareness of the heartbeat), anxiety, and other symptoms associated with the “fight or flight” response. When MVP causes these symptoms, it is referred to as dysautonomia syndrome.
