I'm a 36 year old female that dropped dead at work (Thank you ambulance service) I have been diagnosed with ventricular fibrillation, with no known cause. All tests, angiograms, Xrays, echocardiograms, etc., have come up negative. We've been wracking our brains, and the thought occured to me that I have always avoided certain wine coolers because they made my heart race. Has anyone ever heard of any allergies that cause heart problems? Or what ingredient it is in wine coolers that might be a problem? Everytime my heart flutters, it's about a half hour after eating. I've looked online but can't seem to find anyone that has heard of this.
