After 45 years of suffering frequent PVC's I met a doctor who suggested magnesium citrate. I also dragged out the last report from my cardiologist who recommended an anti-depressant, advice which I had previously ignored. So I have been taking both for a few weeks now - 400 mg of Magnesium Citrate (not the phosphate or carbonate or sulphate just the plain citrate) and one 5mg Escitalopram. It's been only a few weeks not but I haven't felt this good in decades. I actually think I am breaking the destructive PVC's cause anxiety which causes depression which causes more anxiety and more PVC'S etc.
From getting hundreds of these every day I have gone down to less than a couple of dozen and no longer spend every waking hour monitoring my heartbeats. Instead of feeling every heartbeat every day I feel like everyone else whose hearts tick away unnoticed in the background. The anti-depressant is non-addictive too.
Hope this helps some of you.
