my mum has been having palpatations for some time, mainly when she lies down in bed at night she hears her heart missing a beat. she went to see a private heart specialist today and has said it is a leaking valve and a murmur. she has not been told anything else really until she goes back in jan for more tests. does anyone have any knowledge of this or experience that could shed some light on the outcome and treatment? obviously i am very very worried
