heart beat and blood pressure

[motta]

Hi, I'm a 25 year-old female. today I checked my blood pressure and heart beat. the readings were 76-50 for blood pressure, and 96 for heart pulses. I was feeling dizzy for the whole day and I couldn't finish any of my studies and my chores. I'm not taking any medicatoins for blood pressure or heart beatings and until now I couldn't find a time to go to a clinic or health center to check whether I do have a serious problem or not. I heard that high hearts pulses is usually associated with high blood pressure. but in my case, how come my heart beats is high while my blood pressure is low? is there something wrong?

Your blood pressure is abnormally low and you should be evaluated by a doctor.  The most common cause can be fever, hyperventilation, dehydration, and severe infections. Also, the excessive use of diuretics, vasodilators, or other types of drugs, and people with anemia.

Yes, a heart disease can cause high blood pressure and a concomitant fast heart rate.

there is the "pressure x rate constant"

i.e., your body wants to preserve a certain amount of blood flow. As an example, if BP goes down, the HR can increase in what's called 'reflex tachycardia". It's like a seesaw effect. Or vice versa.

Of course, some things can make both rise at the same time, like caffeine or nicotine.
