I had varying rates of PVC's. I think it was mostly stress related as my brother had died and I'm the executor of his estate. My cardiologist told me to increase Metoprolol. It was 1/2 pill due to having Bradycardia. I am doing relaxation techniques. I'm eating pumpkin seeds and assorted nuts to get Magnesium. My PVC rate went to zero during the last month. I check it twice a day with Kardia Mobile.
