heart health product

I reviewed this product in the past---I use it as an assist for CAD - I'm not sure how to tell if it is working , but know it is not causing any adverse effects. I'm 72 & have been a heart patient for 21+ years. Been using this product for 6-8 months

Regular heart rhythm

L-arginine and Taurine along with the medice, Dofetilide, have helped keep my heart beating regularly. Once I stopped taking those two amino acids and my irregular heartbeat returned. About 4 days after I resumed taking the amino acids my heartbeat returned to regular rhythm.
