Low blood pressure diagnosis are tests to evaluate the low blood pressure cause; identify any heart, brain or nervous system problem.
8 Low blood pressure diagnosis tests
- Blood tests: can provide information about the overall health; you may have low blood sugar (hypoglycemia), anemia, an underactive or overactive thyroid gland, adrenal insufficiency, determine the presence of infection, vitamin B-12 or folate deficiency, and anemia. All of which can cause low blood pressure.
- Urine tests: Urine microscopy and culture for evidence of any infection.
- Electrocardiogram (ECG, EKG): This non-invasive test to detect irregularities in the heart rhythm, structural abnormalities of the heart, problems with the supply of blood and oxygen to the heart muscle. It can also tell if having a heart attack or have had a heart attack in the past. During the procedure, small electrode patches attached to the person's chest, arms, and legs that transmit heart's electrical activity to a monitor.
- Holter and event monitor: They are small, portable devices you can wear while you do normal daily activities. It records the heart's electrical activity similar to an EKG. An EKG records the heartbeat only for a few seconds. Holter record the heart for longer periods than an EKG; EKG might miss detecting heart rhythm problems not occurred during the test.
- Echocardiogram: This test is similar to an ultrasound used in pregnant women. An echocardiogram uses sound waves to produce images of the heart that may show structural abnormalities in the heart muscle or valves as well as abnormalities in the heart rhythm.
- Stress test for hypotension diagnosis: Some heart problems which can cause low blood pressure are easier to diagnose when the heart is working harder than when it is at rest. During a stress test, the patient should exercise, such as walking on a treadmill. Alternatively, may be given medication to make the heart work harder for those who unable to exercise. When the heart is working harder, the health professional will monitor the blood pressure and heart (with echocardiography). Electrodes on the patient's chest to monitor the heart’s electrical activity.
- Valsalva maneuver for low blood pressure test: This test checks the functioning of the autonomic nervous system by analyzing the heart rate and blood pressure. This test should take after several cycles of deep breathing; take a deep breath and then force the air out through the lips, as if trying to blow up a stiff balloon.
- Tilt-table low blood pressure test: If you have low blood pressure on standing, or from faulty brain signals (neurally mediated hypotension), the doctor may suggest a tilt-table test, which evaluates how the body reacts to changes in position. During the test, the patient should lie on a table that is tilting to raise the upper part of the body. The blood pressure is monitored during the test to determine how the patient's body reacts to changes in position.
