I have pvcs that seem to start every 3 weeks(approx) and stick around for a couple of weeks and then go away until the next cycle. I have runs of them and have been put on Metoprolol 25 mg. This worked for awhile but stopped working recently, so I tried taking passionflower extract in addition. This worked well and strangely I wake up in the morning without pvcs and they only start about 1 hr AFTER I take my daily dose of Metoprolol. Can the beta blocker cause PVCs? Please let me know if you have run into this. I also worry about my liver with any medication since I have Hep C
(early stage). Thanks.
