is there a link with vitamin D and heart twitchings

My 20 year old daughter has had what she says is heart twitching. She is an Indian classical dancer. She does vigorous dance practice (almost 1 1/2 hours 4 to 5 times a week). Since age 18 or so she has been saying this twitching. We took her to so many cardiologists who did EKG,ECG, heart halter monitor, ultrasound. They just say that she probably just has some extra beats. She claims that lately she has been feeling it more, especially when she dances. PLEASE HELP. Running out of conclusions and ideas. Should I have her checked for vitamin D deficiency? We now live in a fairly mild climate but winters it does get cold. She is a vegetarian also.
