fifty year old woman/slightly overweight...Have been experiencing odd symptoms past month...pain in left shoulder, arm,chest,jaw; palpitations; dizziness; ... have mitral valve prolapse. Stress and echo showed mild abnormalities. No history of hypertension but when went to cardio for follow up BP was 170/110 so was placed on hypertensive med. for past 2 weeks with follow up in 1 month. BP has consistently been low 100/60 s since starting meds. Do I need to be alarmed with this reading and call cardiologist regarding these low BP readings...have been feeling very lethargic and abnormally fatigued.
