Last fall I have been experiencing a rapid heart rate during distance running and cycling. My garmin was showing extended periods of 220 bpm, and the test was replicated at the cardiologist's on a cardiac stress test. Within five minutes of meeting me/seeing my test he diagnosed me with Ventricular Tachycardia and that I should get an ablation immediately. Nervous about the operation (I am healthy 25 yr old female marathon runner), I decided to get some blood work done from regular physician. My test revealed very low ferritin levels and blood count, my doctor told me that my blood volume was 66% of what it needed to be. I do not have heavy periods and eat only grains, vegetables, fruit, and 1/2 -1 lb meat a day to fuel my exercise. I have been taking iron three times a day and a month later, my iron has improved but my blood count has not. How long can I expect before the blood count is up? Should I be even more concerned than these two symptoms? What should I be looking for? I completely distrust both my doctors since my cardiologist told me that I just developed the arrhythmia out of the blue and nothing could've caused it, and he has not even followed up with me unless I want the ablation. More advice would be great! Thank you
