Glaxony,
if I were you I would take a good quality Colloidal Silver of at least 30ml three times per day on an empty stomach, making sure that you swish this around your mouth for at least 30secs before swallowing: do this for at least 2 weeks. This will address your Hep C, Hep A, Herpes Simplex, Herpes Zoster and Epstein Barr in your system.
For your tachycardia, I would take a good quality absorbable magnesium supplement along with a good quality CoQ10 or Coenzyme Q10. Both of which are critical for heart health
This is in my view the best magnesium, as Dr Carolyn Dean MD ND is an expert on magnesium......... http://drcarolyndean.com/resources.html
