Cardiac Diagnostic and Nuclear Procedures
Testing and imaging of the heart and blood vessels is an important diagnostic
tool for your physician. At MHMG our Cardiology Testing and Nuclear Medicine
department has a full scope of up-to-date equipment along with an experienced
staff of highly trained registered nurses and technologists to perform
a wide range of tests. Results are interpreted by a MIMG Cardiologist
who produces a comprehensive report to assist your physician in the management
of your care.
The departments accolades include the first facility in California to
be accredited the International Commission of Nuclear Cardiology Laboratories.
Our research investigations have advanced the cardiology field with results
being published in prestigious medical journals an presented at medical
conferences on three continents. The Cardiac Diagnostic department has
been serving South Orange County for over three decades and the Nuclear
Medicine Department was opened in 1995.
We have several different diagnostic studies and procedures including:
- Holter Monitor
- Event Monitor
- Nuclear Medicine
- Stress Tests
- Resting MUGA
Echocardiography is a method of imaging the heart through ultrasound. The
test takes about 30 minutes, is painless, and does not require an IV.
During this test, you will lay on your left side and a technician will
apply ultrasound gel to your chest, then place an ultrasound probe to
your chest to visualize the heart using sound waves. The ultrasound equipment
is similar to that used to obtain images of the fetus in a pregnant woman's
uterus. An echocardiogram gives your doctor information about your heart
muscle and heart valves, but cannot diagnose coronary artery disease.
A holter monitor is a device used to diagnose the presence of cardiac rhythm
abnormalities. The device is a small box that is worn around your waist.
The box is connected to seven leads which the technician will place on
your chest and stomach. You will wear the monitor for 24 hrs, during which
time the monitor will record your heart rhythm. While wearing this monitor
you will need to keep a diary of your activities and symptoms throughout
the 24 hrs. You may not shower while wearing the monitor. At the end of
the 24hrs you will remove the leads from your chest and stomach and turn
the monitor in. The monitor recording will then be analyzed.
The event monitor is a device used to diagnose the cause of cardiac rhythm
abnormalities. Over 4 million Americans have arrhythmia, a common condition
in which the heart beats at an irregular pace. Individuals experience
arrhythmias differently, but the most common symptoms include; palpitations
or fluttering of the heart, shortness of breath, fainting or dizziness
and chest pain.
Most arrhythmias occur infrequently so they are hard to detect during
a short office visit. In order for the physician to obtain complete information
regarding the patient's condition, an Event Monitor is prescribed
to allow the heart rate to be captured when the patient feels a symptom.
It is worn for 30 days, while it automatically records any changes in
your heart rhythm. The patient is encouraged to continue their daily routine.
At end of the prescribed period, the monitor is returned and the information
is processed. A Cardiologist will review the data and prescribe the best
course of treatment for the patient.
A nuclear stress test helps measure blood flow to your heart muscle at
rest and during stress. It is similar to a routine exercise stress test
but with images in addition to electrocardiograms.
During a nuclear stress test, a radioactive substance is injected into
your bloodstream. This substance mixes with your blood and travels to
your heart. A special camera or scanner which detects the radioactive
material in your heart creates images of your heart muscle. The two most
common tests are:

Resting MUGA studies are used to assess the pumping efficiency and motion
of your heart. This test takes approximately 60-90 Minutes. You will be
taken back to the testing room by the nuclear medicine technologist who
will explain the test in detail. The technologist will start an IV and
draw a small amount of blood. This blood will be labeled with a radioactive
isotope and then re-injected into the IV. The isotope does not have any
side effects and the amount of radiation that you are exposed to is very
small. Once the labeled blood is re-injected, you will be placed on the
camera and images will be taken. This will take about 30 minutes. It is
very important that you remain still under the camera as any motion will
reduce the quality of the images greatly.
Once the camera has stopped, the IV will be removed and you will be finished
with the test.
