I hope your mother is okay. I was having some problems with irregular heartbeat. An Ayurvedic herb called Arjuna helped me. Also I started drinking green tea. I also bought some capsules that contain ground up beef heart from grass-fed cows. I don't know what's causing your mother's arrhythmias, but sometimes people in integrative medicine can diagnose trick things. You can find an MD who practices integrative medicine on IFM.org. Good luck
Eliabe, I am praying for you....Lord please send Healing, Blessing, and Protection.
Dear Elizabe from Brazil, I pray God will heal your mother. Lord God, take away the cardiac arrhythmia and replace it with Your joy and peace. I humbly lift up this prayer in the mighty name of Jesus I pray. Amen
