You have mitral and tricuspid valve
regurgitation with atrial fibrillation
with normal sinus ventricular heart rate.since you have chest discomfort
(Angina/dyspnea ) on exertion ,with dizziness and extreme fatigueness , I suggest to consult your cardiologist and get evaluated, including 2D echo and coronary angiogram and based on it further planning of conservative management or valve replacement
to be considered.
