question: I am a 44yrs have been diagnosed with a murmur for many years now and used to have regular black outs  when I was 2yrs -15yrs that I suspect were related to this condition and used to also get heart palipations.I currently feel this condition through heart palpitations, dizziness, light headedness, fatigue and sometimes nusea. Recently my workload plus my studies have increased and so is my intake of energisers to keep up with the increased work. I am currently getting palpitations regularly despite the fact that I am on chronic medication. I am anaemic and my blood is always very low. My Doctor sometimes  prescribes iron supplements. I am currently exercising thrice a week. What must I do to reduce the frequency of palpitations? Please advice.
