Whether you are
experiencing symptoms
of heart disease or are
at risk for developing
heart disease, your
doctor may recommend
one of several
diagnostic tests. Here
are some of the more
common heart and
cardiac diagnostic
testing options Dearborn
Cardiology provides.
Electrocardiography
EKG (Electrocardiography) is the
process of recording the electrical
activity of the heart over a period
of time using electrodes placed on
the skin. These electrodes detect
the tiny electrical changes on the
skin that arise from the heart
muscle's ElectroPhysiologic pattern
of depolarizing and repolarizing
during each heartbeat. It is a very
commonly performed cardiology
test.
Holter Monitor
Holter monitor is a battery-
operated portable device that
measures and tape record 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.
Echocardiogram
An echocardiogram is a test that
uses ultrasound to measure heart
muscle and heart valves.
Stress Echocardiogram
This is an echocardiogram that is
performed while the person
exercises on a treadmill or
stationary bicycle. This test can be
used to visualize the motion of the
heart's walls and pumping action
when the heart is stressed. It may
reveal a lack of blood flow that
isn't always apparent on other
heart tests. The echocardiogram is
performed just prior and just after
the exercise.
Dobutamine Stress
Echocardiogram
This is another form of stress
echocardiogram. However, instead
of exercising to stress the heart,
the stress is obtained by giving a
drug that stimulates the heart and makes it "think" it is exercising.
The test is used to evaluate your
heart and valve function when you
are unable to exercise on a
treadmill or stationary bike. It is
also used to determine how well
your heart tolerates activity and
your likelihood of having coronary
artery disease (blocked arteries)
and evaluates the effectiveness of
your cardiac treatment plan.
Treadmill Stress Test
An exercise stress test usually
involves walking on a treadmill
while your heart rhythm, blood
pressure and breathing are
monitored. Your doctor may
recommend an exercise stress test
if he or she suspects you have
coronary artery disease or
irregular heart rhythm (arrhythmia).
Cardiolite Stress Test
A Cardiolite stress test is a
diagnostic exam used to evaluate
the supply of blood to your heart
muscle. Your heart receives blood
from the coronary arteries. If
these arteries become partially
blocked or narrowed, your heart
will not receive the blood that it
needs for proper function. This
test may be useful in detecting the
presence and significance of
coronary artery disease.
Lexiscan Stress Test
Lexiscan stress test is a medicine
that is used during a nuclear heart
stress test to dilate, or open up,
the arteries. All normal arteries
are able to do that. But if you
have a blocked artery, it cannot
dilate. When doctors order cardiac
imaging tests, they are looking for
the relative lack of blood flow.
ABI Test
ABI The ankle-brachial pressure
index (ABPI) or ankle-brachial
index (ABI) is the ratio of the blood
pressure at the ankle to the blood
pressure in the upper arm
(brachium). Compared to the arm,
lower blood pressure in the leg is
an indication of blocked arteries
due to peripheral artery disease
(PAD).
Lower Extremity
Arterial Duplex
Lower extremity arterial duplex is
an ultrasound evaluation of the
blood flow to the arteries in the
legs and is used to detect and
measure the amount of narrowing
of the arteries.
Lower Extremity
Venous Duplex
Lower Extremity Venous duplex is a
procedure that uses sound waves
to "see" inside your body. This
procedure is performed to evaluate
symptoms including leg pain or
swelling, excessive varicose veins,
shortness of breath, or suspected
blood clots in your legs and/or
lungs.
Renal Duplex
Renal Duplex is a Color flow Doppler
of kidney and renal artery. The
renal arteries provide blood flow
to the kidneys. Renal artery
disease, including narrowing
(stenosis) due to atherosclerosis,
can result in reduced blood-flow to
the kidney. This can cause
hypertension (high blood pressure).
Aortic Duplex
Aortic Duplex is an abdominal
aortic duplex exam. It is a
non-invasive exam that uses high
frequency sound waves to produce
images of the aorta. The exam is
useful for detecting abnormalities
in the artery and provides blood
flow measurements. The exam is
painless and typically takes less
than an hour to complete.
Carotid Duplex
Carotid duplex is an ultrasound
test that shows how well blood is
flowing through the carotid
arteries. The carotid arteries are
located in the neck. They supply
blood directly to the brain.
Ultrasound is a painless method
that uses sound waves to create
images of the inside of the body.
