Can you tell me what my blood pressure should read for my age many thanks  <response>: Dear, A normal blood pressure usually ranges from 110-140 60-90, but 15385 indicates hypertension, concerning your weight you should be around 65 kg. so you are overweight. But to say that you are a hypertensive patient you should your blood pressure in many times for 3 days, if it is high, so you have hypertension. Also familial history plays an important role .you should start with lifestyle changes :1- decrease salt containing foods .2- decrease high fatty meals .3- stop smoking if you are smoker.4- do exercise for 30 minutes a day or walk for 1 hour.about your palpitations, what kind is it ? Is it regular or not ? How many attacks you notice ? . I think you need an ECG to roll out your rhythm .you should visit your doctor simply putting your mind that changing your lifestyle is the key, otherwise a small dose of beta blocker may be recommended. Thanks
