High Heart Rate and Low Blood Pressure
- Ups and Downs in Life
With the help of this article, we invite you to figure out what is dangerously low blood pressure, when low blood pressure is an emergency, and, consequently – whether it is urgent to "raise" it. Additionally, some info regarding the high heart rate and its link to blood pressure is provided.
While high blood pressure, referred to as arterial hypertension, and may be more common in the everyman's discussion of morbidities, low blood pressure still exists as well. It often causes problems of its own, and those may even include unlucky fatalities. Well, then, how low is too low for blood pressure? What are the reasons for low blood pressure, and how to counteract them? Let's discover.
Routine measuring and analysis of the blood pressure
I would like to start with the brief premise: the knowledge of the normal blood pressure and other nuances of the cardiovascular system is not very useful apriori, should you not adopt it practically. As such, the best path to practical integration is to use both the blood pressure check app – welltory.com - and the heart rate app at one. Such an app includes plenty of functionality, including tracking your heart rhythm and blood pressure, sophisticated blood pressure charts, and – last but not least – heart rate variability (HRV) analysis.
Heart rate variability may be a terra incognita for you now, so to answer "What is HRV?" don't hesitate to check out this brilliant article regarding the topic. Welltory is mainly considered the best heart rate variability app, and its specialists did a great job explaining the concept of HRV.
What is low blood pressure anyway?
Blood pressure is the intensity with which blood presses against the walls of the blood vessels. If you are questioning, "What is systolic blood pressure" – it's the highest pressure at the moment when the heart contracts. On the other hand, in the interval between heartbeats, the pressure in the vessels drops – it is called lower or diastolic.
Normal systolic blood pressure ranges from 90-120 mm Hg, diastolic – from 60-80. So, if the readings are less than 90/60, the pressure is considered low. This condition is also medically called hypotension.
Low pressure, high pulse
Low blood pressure quite often causes abnormally fast heart rhythm. It is due to the organism's homeostasis systems. Organism feels the hypotension by the baroreceptors of the carotid glomus and thus sends the signal to compensate for it.
And, indeed, one of the compensatory reactions to improve the overall blood supply and blood flow is accelerated heartbeat.
Is low blood pressure dangerous?
Many people – often slim women – live with hypotension for years and feel themselves okayish. Doctors believe that these people are lucky: they are less likely to suffer from cardiovascular diseases.
However, if the pressure suddenly drops below normal levels, unpleasant symptoms may appear:
- blurry vision;
- nausea or vomiting;
- a feeling of weakness.
As a rule of thumb, at a young age, the health risk is not associated with the low blood pressure itself but with the reasons due to which it falls. The exception is fainting. If hypotension is accompanied by loss of consciousness, you should definitely see a doctor.
But for older people, low blood pressure can be hazardous. Moreover, a drop in diastolic pressure is more dangerous than a decrease in systolic pressure. This is because it can lead to impaired blood supply to the kidneys and brain, increasing the risk of stroke and kidney failure.
What causes hypotension?
The idiopathic, non-persistent hypotonia can be caused, for example, by:
Sudden change of body position
It is called orthostatic hypotension. When a person takes an upright position, gravity rushes blood to the legs and abdomen, and the pressure in the vessels drops. In order to raise blood from the legs and normalize blood pressure, the autonomic nervous system increases the heart rate and compresses blood vessels.
Healthy people do not experience unpleasant sensations, but in some cases, the autonomic nervous system fails. As a result, the pressure drops, the blood does not have time to rise from the legs, the brain lacks oxygen, and symptoms of hypotension appear.
Sometimes such sensations arise in healthy people, for example, because of the heat, and there is nothing to worry about. But if you feel dizzy every time you change your posture, a visit to the physician is advised.
After eating, blood rushes to the gastrointestinal tract, and so that the pressure does not drop too much, the autonomic nervous system constricts the vessels and increases the heart rate. However, about a third of older people cannot cope with such a load. This condition is called postprandial hypotension. If this happens, the help of a doctor is needed.
Growing too fast
As you might guess, the problem most often occurs in children and adolescents: due to the rapid growth, a failure occurs in the autonomic nervous system. As a result, when you change posture or bend over, symptoms such as dizziness and fainting appear. It is called neuro-mediated hypotension. Children usually outgrow the problem, and hypotension goes away on its own.
How to turn blood pressure from low to normal?
If your blood pressure is consistently below normal, but you feel good, you have no problem. On the other hand, if your symptoms include nausea, dizziness, or fainting, you need to see a doctor.
You won't be able to solve it out on your own: low blood pressure can be a symptom of various diseases, and to find out the actual cause, you need to be tested and examined. This is very important because the method of treatment depends on the diagnosis.
But there are general recommendations that human beings should follow in case of hypotension:
- Give up bad habits;
- Get plenty of fluids and salt;
- Avoid situations that provoke hypotension;
- Sit or lie down at the first symptoms of hypotension.
