I was diagnosed with mild mitral valve prolapse and tricuspid valve reguitation(also mild) but with symptoms.should I worry? Dr. said I should not worry about it. However, I have  severe symptoms like giddines,light headed, arrythmia and fainting. I am also implanted with pacemaker-dual chamber april 2011 for the sick sinus syndrome. please help
These are not probably due to mitral valve prolapse rather due to sick sinus syn Chat Doctor.  You should get pacemaker interrogated and doctor will change certain settings like increasing rate a bit, may lead to resolution of symptoms.
