I started taking a multi vitamin and i feel like this has helped reduce my pvcs drastically. is this possible?

Yes: yes posible but vitamins donot usually affect PVCS

Sure: Sometimes different vitamins and even small alterations in electrolytes may be responsible for abnormal heart beats, and as well anxiety can cause them, so by taking the vitamin, you may feel less stressed and also be replacing possible deficiencies in your body. I am glad you feel better, be sure to tell your Doctor all the meds you take, even the over the counter one.

You'reNowOnA PVCDiet: Who cares,it worked(maybe)and vitamins in proper dose can't hurt(much).We could theorize that it was the magnesium in there,if listed,but probably not.Or it was a serendipitous event,or you've found the right placebo for you.Or whatever medications you are taking,if any,are starting to work,or,or,any combination.Now it's time to see if it lasts;and if it does,stop the vitamin and see what happens.

Yes, placebo effect,: reason all clinical trials compare with placebo. Placebo effect: Very Real; your experience demonstrates this: Study: http://goo.gl/4YdKsa Vitamins=compounds so common in most foods that humans have not maintained all genes/enzymes needed to manufacture them from other molecules. Clinical trials have not shown consistent clinical benefits from taking MVits, See: http://goo.gl/hTgfHM for a summary.

Yes: Over half of Americans are deficient in folate, (folic acid) Vitamins A, D & E, calcium &magnesium and over 2/3 are deficient in C, B6 & zinc. No one really knows the cause of most cardiac arrhythmias including PVC's, but vitamins & minerals are important for heart function. A study by Dr. Mathias Rath found very impressive reductions in arrhythmias with vitamins. See http://tinyurl.com/nudkeke for details.
