Hi, im a 14 year old female and for awhile I have been having consistently high dialostic blood pressure. I'm diagnosed with mitral valve prolapse, and possible innapropriate sinus tachycardia. Could these conditions have anything to do with the high BP? Today my reading was 115/95 about an hour after I woke up, and I've realized that my pulse pressure is apparently low. My systolic number is 99% of the time normal but there has been a few times of it being 130+, while my dialostic is usually 85-95. Is there anything that causes low pulse pressure and should i be concerned? Thanks
