Ankle-brachial index test is a comparison of your blood pressure measured at an ankle and your blood pressure measured at an arm, which can indicate blockage of blood flow to the legs.
After removing your socks and shoes you will lie on an examining bed. The technician will attach blood pressure cuffs to arms, ankles, and toes. The sonographer will warn you when the cuffs inflate.
You can take the following steps to prepare for your appointment:
An echocardiogram uses sound waves to produce images of your heart. This commonly used test allows your doctor to see how your heart is beating and pumping blood. Your doctor will look for heart size, pumping strength, damage to the heart muscle, valve problems, and heart defects.
Transthoracic echocardiogram is a standard, noninvasive echocardiogram. A technician (sonographer) spreads gel on your chest and then presses a device known as a transducer firmly against your skin, aiming an ultrasound beam through your chest to your heart. The transducer records the sound wave echoes your heart produces. A computer converts the echoes into moving images on a monitor. Doppler echocardiogram is when sound waves bounce off blood cells moving through your heart and blood vessels, they change pitch. These changes (Doppler signals) can help your doctor measure the speed and direction of the blood flow in your heart. Doppler techniques are used in most transthoracic echocardiograms, and can check blood flow problems and blood pressures in the arteries.
After undressing from the waist up, you'll lie on an examining bed. The technician will attach sticky patches (electrodes) to your body to help detect and conduct the electrical currents of your heart. During the echocardiogram, the technician will dim the lights to better view the image on the monitor. You may hear a pulsing "whoosh" sound, which the machine is recording the blood flowing through your heart. Most echocardiograms take 45 minutes, but the timing may vary depending on your condition. During a transthoracic echocardiogram, you may be asked to breathe in a certain way or to roll onto your left side. Sometimes the transducer must be held very firmly against your chest. This can be uncomfortable — but it helps the technician produce the best images of your heart.
No special preparations are necessary for a standard transthoracic echocardiogram.
The primary purpose of a carotid ultrasound is to screen for a narrowing of the carotid arteries that indicates an increased risk of stroke. Narrowing is usually caused by plaques — a buildup of fats, cholesterol, calcium and other substances that circulate in the bloodstream. Early detection of narrowing of the carotid arteries enables your doctor to begin treatments that improve blood flow to the brain and decrease your risk of stroke.
Other uses of carotid ultrasound: your doctor also may order a carotid ultrasound to:
You can take the following steps to prepare for your appointment:
During the procedure you'll likely lie down on your back during the procedure. The ultrasound technician (sonographer) may gently adjust the position of your head to improve access to the side of your neck. The sonographer will apply a warm gel to your skin above the site of each carotid artery. The gel helps eliminate the formation of air pockets between your skin and the transducer. The sonographer then gently presses the transducer against the side of your neck in order for the instrument to send and receive sound waves. You shouldn't feel any discomfort during the procedure. If you do, tell the sonographer. A carotid ultrasound usually takes about 15 to 30 minutes.
Vascular ultrasound is a noninvasive ultrasound method (also called a duplex study) used to examine the blood circulation in the arms and legs. Non- invasive means the procedure does not require the use of needles, dyes, radiation or anesthesia.
During a vascular ultrasound, sound waves are transmitted through the tissues of the area being examined. These sound waves reflect off blood cells moving within the blood vessels, allowing the reading physician to calculate their speed. The sound waves are recorded and displayed on a computer screen.
Your physician has recommended that you have this test to evaluate the blood flow to specific part in your body. Vascular ultrasound can be used to evaluate:
Your ultrasound test is performed by specially trained technologists and interpreted by your cardiologist. You will lie on the bed during the test. A small amount of water-soluble gel is applied to the skin over the area to be examined. The gel does not harm your skin or stain your clothes. A small device called a transducer is placed over the gel-coated area to be examined. The transducer produces images on the ultrasound screen. There may be some minor discomfort during the exam when the technologist applies pressure to your arms or legs. You may hear noises when the technologist listens to the blood flow and records the measurements.
The ultrasound takes about 30 to 45 minutes to complete.
There is no special preparation before the test
Some heart problems — particularly those involving the coronary arteries that supply blood to your heart muscle — occur only during physical activity. For a stress echocardiogram, ultrasound images of your heart are taken before and immediately after walking on a treadmill. If you're unable to exercise, you may get an injection of a medication to make your heart work as hard as if you were exercising.
After undressing from the waist up and putting a gown on. The treadmill technician will attach sticky patches (electrodes) to your body to help detect and conduct the electrical currents of your heart. The sonographer will obtain images of your heart (left ventricle) before getting on the treadmill. The cardiologist will then be present when you're on the treadmill. We will encourage you to do your best, if you have trouble on the treadmill just tell us. We are trying to get your heart rate to a certain point. Once you reach that point we ask that you lie on the bed and the sonographer will obtain images of your heart beating fast.
During a stress echocardiogram, exercise or medication — not the echocardiogram itself — may temporarily cause an irregular heartbeat. Serious complications, such as a heart attack, are rare.
If you'll be walking on a treadmill during a stress echocardiogram, you should wear:
A duplex ultrasound is a test to see how blood moves through your arteries and veins.
A duplex ultrasound combines:
There are different types of duplex ultrasound exams. Some include:
You may need to wear a medical gown. You will lie down on a table, and the ultrasound technician will spread a gel over the area being tested. The gel helps the sound waves get into your tissues.
A wand, called a transducer, is moved over the area being tested. This wand sends out the sound waves. A computer measures how the sound waves reflect back, and changes the sound waves into pictures. The Doppler creates a "swishing" sound, which is the sound of your blood moving through the arteries and veins.
You need to stay still during the exam. You may be asked to lie in different body positions, or to take a deep breath and hold it.
Sometimes during a duplex ultrasound of the legs, the health care provider may calculate an ankle-brachial (ABI) index. You will need to wear blood pressure cuffs on your arms and legs for this test.
The ABI number is obtained by dividing the blood pressure in the ankle by the blood pressure in the arm. A value of 0.9 or greater is normal.
Usually, there is no preparation for this test.
If you are having an ultrasound of your stomach area, you may be asked not to eat or drink after midnight. Tell the person doing the ultrasound exam if you are taking any medicines, such as blood thinners. These might affect the results of the test.
You may feel some pressure as the wand is moved over the body, but there is no discomfort most of the time.
A duplex ultrasound can show how blood flows to many parts of the body. It can also tell the width of a blood vessel and reveal any blockages. This test is a less invasive option than arteriography and venography.
A renal duplex ultrasound can also be used after transplant surgery. This shows how well a new kidney is working.
Your doctor may recommend you have an ultrasound of the aorta if you're at risk of an abdominal aortic aneurysm. Aortic ultrasound screens for a potential abdominal aortic aneurysm, an enlargement or ballooning of the large artery that supplies blood to the abdomen, pelvis and legs.
Risk factors for abdominal aortic aneurysm include:
Food and liquids in your stomach can make it difficult for the ultrasound technician (sonographer) to get a clear picture of your aorta. Fasting instructions will be given before the exam.
DAY BEFORE EXAMINATION: Clear liquids at noon and evening meals. Eat no solid foods. Drink four 8-ounce glasses of water between 1:00 p.m. and 9:00 p.m.
At 5:00 p.m., drink one bottle (10 ounces) of Citrate of Magnesia.
At 8:00 p.m., take two Biscodyl (Dulcolax) pills.
Nothing to eat or drink after midnight (may take medications with water at anytime).
A Holter monitor is a battery-operated portable device that measures and tape records your heart’s activity (ECG) continuously for 24 to 48 hours or longer depending on the type of monitoring used. The device is the size of a small camera. It has wires with silver dollar-sized electrodes that attach to your skin. The Holter monitor and other devices that record your ECG as you go about your daily activities are called ambulatory electrocardiograms.
“I thought wearing the monitor at night would be very uncomfortable, but the cord was long so I could put it on the nightstand. I made sure the electrodes were on tight before I went to bed.” Sarah, age 62.
Regular electrocardiograms (ECGs or EKGs) let your doctor look at your heart’s activity at one point in time during your ECG test. But abnormal heart rhythms and cardiac symptoms may come and go. That’s why your doctor may want to evaluate your heartbeat over time while you go about your normal activities. You may be asked to wear a Holter monitor if you have fast, slow or irregular heartbeats called arrhythmias.
Wearing a Holter monitor has no risks and causes no pain. Holter monitors have wires that connect to small discs (electrodes) attached to your chest to record the electrocardiogram. Because the electrodes are attached with tape or adhesives, they may cause mild skin irritation. Tell the technician if you are allergic to any tapes or adhesives.
A specially trained technician will attach the Holter monitor and instruct you how to record your symptoms while wearing it.
Do your usual activities while you wear the monitor with these exceptions:
What happens after wearing a Holter monitor?
After the test period, return the monitor to the technician. He or she will process the record of your heart activity and prepare a report for your doctor. This will include the notes in your diary. You should get the results of the test in one or two weeks.
