Hi, I am a 44 year old female with a history of WPW; ablation in 1994 (successful). Three weeks ago, I had a hysterectomy. About 4 days after, I started having PVC s. I ve had them in the past, but never this bad. I have about 10-15/minute. Sometimes I feel SOB if they last too long, but most days I get a reprieve for a few hours. I notice they are worse if I lay in my right side or back. I ve read about Calcium and Magnesium supplements, and wanted your thoughts. Thank you, Laurie
