Low Blood Pressure & High Heart Rate Symptoms, Causes & Treatment

The human heart is the most active organ in your body. Apart from it, all the other vital parts of your body get some time to rest and regain their strength, while the heart is always working and pumping blood to all the parts of your body. Even when you are sleeping, your heart is working to ensure blood supply to your body.

Blood pressure and heart rates are directly related. When you are suffering from low blood pressure, heart muscles have to work more to send blood to your body and thus the heart rate increases. The measure of blood pressure is alarming when it gets below 90 millimeters of mercury (systolic measure) and 60 millimeters of mercury (diastolic measure). Heart rate denotes the number of times your heart beats in one minute. For a normal healthy adult, safe range of heart rate is between 60 and 100 beats in one minute. Any variations from this normal range can be dangerous for your health as it can also become a reason behind heart attack.

In this article, we will analyze the major reasons behind low blood pressure and high heart rate. Further, we will also suggest some treatments for this problem.
