My 21 year old girl has a rapid heart beat, which started recently. she is taking
Contraceptive pill, 5 days ago we rushed her to A&E, her heart beat was very fast, they said she had inner ear infection and her tonsils were inflamed, so she was given Antibiotics but we had to stop as the tablets were making her worse.(heart beat).
while we were in hospital they recommend that she should take Magnesuim tablets. can you please advise why all of a sudden she is having this problem?
