Low blood pressurealso calledhypotensionmay not be a medical concern unless it causes symptoms.
A high heart ratecalled tachycardiais one way the heart resolves hypotension.
This article will discuss the benign and serious causes of when tachycardia and hypotension occur together.

It will also cover when to contact a healthcare provider and potential treatments.
A person’sblood pressureand heart rate should correlate with their actions.
If someone is resting, their heart rate and blood pressure should be on the lower end of normal.
When someone exercises, both their heart rate and blood pressure should be raised.
This is a normal body process.
However, a high pulse and low blood pressure can indicate an underlying condition.
There are benign causes that resolve with simple treatments.
Learn more about these below.
Theautonomic nervous systemregulates involuntary physical processes like heart rate, blood pressure, breathing, and digestion.
POTS symptoms can include:
POTS can change a person’s life, but it is not life-threatening.
The most significant risk associated with POTS is fainting and falling.
POTS treatment varies and is based on underlying conditions and symptoms.
There is no cure but it is treated with diet, medications, and exercise.
It is normal for a slight blood pressure drop when moving to a standing position.
Blood pools in the legs, and there is less blood for the heart to pump throughout the body.
This causes a temporary drop in blood pressure and most people will not even notice it.
The heart will beat faster to bring blood pressure back up to normal.
Dehydration
Another benign cause of low blood pressure and high heart rate is dehydration.
Dehydrationis when there is not enough fluid in the body.
Illness, sweating, diarrhea, vomiting, or not drinking enough can cause it.
When there isn’t enough fluid in the body, blood pressure can decrease and heart rate can increase.
Whendehydrationis mild, it can be treated by consuming additional fluids.
The heart will beat faster to compensate for the decreased blood pressure.
This will help return the blood pressure to normal.
This results in less oxygen and fewer nutrients reaching the organs and tissues, leading to decreased organ function.
If shock is not quickly treated it can lead to death.
The dangerously low volume in the blood vessels causes low blood pressure.
This can cause the heart to pump blood throughout the body ineffectively.
There is decreased blood flow to organs, which can cause many serious problems.
CHF can be because of other medical conditions or by injury to the heart muscle.
It is one of the ways the body works to bring the blood pressure back up to normal.
In mild cases, treatment can be done at home.
However, those with moderate to severe symptoms will likely need to be hospitalized for treatment.
Some people will recover with no treatment, whereas others will need to be in the hospital for treatment.
Some conditions can be treated with at-home treatments such as increased fluid intake and rest.
Other conditions like irregular heart rates are very serious and will need immediate medical attention.
Contact a healthcare provider if a high pulse and low blood pressure are suspected.
They will be able to evaluate and provide prompt, effective treatment.
