This is actually pretty common. One not-to-difficult-to-solve cause could be lack of magnesium...Calcium and magnesium must maintain homeostasis in your blood for TWO very important reasons...calcium causes the heart muscle to contract and magnesium causes the heart muscle to relax. Her-2 folks, in general, are notoriously magnesium deficient (you can check your own levels very simply by looking at the PLATELET count on your most recent CBC...if your platelets are below 300, you are officially Magnesium deficient)...when the levels of mag drop in the blood, too much unbalanced calcium remaining can cause the heart muscle to flutter/spasm...the same way other muscles do when magnesium is low...so try eating a magnesium -rich diet (whole grains, nuts, cocoa, advocados, etc) and I honestly think a PLAIN magnesium tab (but NOT mag citrate) a day wouldn't hurt.

Of course the flutter could be an indication of a more serious underlying condition...so best to keep your onc and primary care physician carefully informed..also, note the time of day the flutters happen and what you were doing and eating or NOT eating or drinking... sometimes, just being sure you are pushing enough fluids and not dehydrating will smooth the flutters out...also, watch your coffee or soda intake as caffeine can be a benign cause of this too, sometimes...:-) Also, remember that it is my educated opinion that her-2 folks should not regularly ingest free calcium supplements as they can make this symptom worsen, as the blood mag to calc ratio is thrown even further out of whack...fyi.

Best of luck to you,
