Hello,

I've being suffering recently from unexplained symptoms such as light-headedness, dizziness, tachycardia, chest discomfort and some dyspnea. I have previously suffered a single episode of what was diagnosed as lone atrial fibrillation when I was 27 years old. I had a echocardiogram following this episode and this confirmed a structurally normal heart. Following this I had another echocardiogram a few months later which showed evidence of trivial mitral regurgitation and the report also stated that the aortic and pulmonary valves velocities were within normal limits but it didn't state if there is was any evidence of regurgitation or stenosis. The tricuspid valve doesn't have any stenosis or regurgitation.

I'm now 31 years of age and have been asymptomatic up until early November this year. I've spoken to my own GP who's arranged a referral to see a Consultant Cardiologist but she seems unconcerned. In this time I've been to A & E twice because of symptoms and an x ray and blood test were performed to check for a minor MI. Both results were negative. No signs of enlargement and no minor MI. The first A & E doctor performed auscultation and said normal heart sounds. On the second visit to A & E the doctor said there was no abnormal heart sound then said there's no significant murmur. I've also used a walk-in centre twice and the GP's on both occasions performed a physical examination and they both said they couldn't detect any abnormal heart sounds.

I have my own due headed stethoscope and have listen and can clearly hear a moderately loud S1 in the left fifth intercostal space. I assume it could be a sign of mitral stenosis? I've learnt a lot about heart anatomy and have studied the structure and function in detail. Further to this I've also read medical journals and case studies.

I feel I have a heart murmur given what the second A & E doctor said. I know some murmurs are classed as functional or innocent but I think with the presentation of symptoms and the development of a new heart murmur that it must be pathological? I also know the previous findings on the echo report are a variation of normal.

I intend to have a cardiopulmonary test and echocardiogram but it's the waiting as my appointment is just over five weeks time. Any expect/professional advice would be appreciated.
