of 2 m/s can be detected during echocardiography
in 60-70% of normal individuals.
Better get your blood hemoglobin
levels checked, as functional murmurs can be appreciated in cases of hyper dynamic circulation like anemia, etc.
But there is no need to worry as it doesn't have much pathological significance.
If everything is normal & symptoms still persist, then it will be better to consult a Cardiologist
Other than that...eat a healthy diet, avoid stress, get good sleep, think positive and stay happy.
Wishing you a Healthy Life.
