PACEMAKER &
DEFIBRILLATOR CLINIC |
|
|
| |
The pacemaker/defibrillator clinic duties
include checking pacemakers and defibrillators for regular
evaluations and reprogramming. |
 |
|
Scheduling follow-up appointments, and
telephonic checks. Pacemaker/defibrillator battery change out
implants are done here in the clinic as well. |
|
Other tasks include: |
|
Holter Scanning |
|
Wound site evaluations for new implant |
|
Keeping an updated patient file system in
the pacemaker art computer and pacemaker/defibrillator patients
charts in file cabinets. |

DIAGNOSTIC TESTS |
|
|
|
Tilt Table |
|
What is
a Tilt Table Test? |
|
If you have had recurrent
syncope (fainting spells), the tilt table test can help determine how
your body responds to changes in position. During the test, you lie
on a table that can be moved to a nearly upright position while your
symptoms, heart rate, and blood pressure are continuously monitored. |
|
What
Does the Tilt Table Test Show? |
|
The tilt table test is
designed to induce (bring on) syncope under controlled conditions. It
is especially useful for diagnosing vasovagal syncope. |
|
What
Happens During the Test? |
|
During the test, you will be
instructed to lay down on a special table, called a tilt table. The
intravenous line is inserted in one arm, and a blood pressure cuff
(or a similar device) is placed on the other arm. The ECG electrodes
on your chest allow the doctor to monitor your heart rhythm. Safety
straps are applied across your chest and legs. You will be
continuously monitored in the tilted position for up to 45 minutes
and then returned to a flat position. |
|
What
Are the Benefits? |
|
The tilt table test helps
doctors determine whether or not you are susceptible to vasovagal
syncope. The information gained from this test helps your doctor make
an accurate diagnosis and develop a treatment plan that's best for
you. |

Echocardiogram |
|
An echocardiogram is a test
that uses ultrasound waves to examine the heart. It is a safe and
painless procedure that helps doctors diagnose a variety of heart
problems. During the test, a transducer (a small microphone-like
device) is held against the chest. The transducer sends ultrasound
waves that reflect echo off the various parts of the heart. The
echocardiogram provides doctors with important information about the
heart. This test can be performed in the doctor's office or at the
hospital. No special preparation is necessary for this test. A
thorough examination usually takes from 20 minutes to an hour,
depending on the number of views and whether the Doppler echo is
used. The echocardiogram is very safe. There are no known risks from
the ultrasound waves. It is also painless, although you may feel
slight discomfort when the transducer is held firmly against the
chest. The major benefit of this test is that it gives information
about the heart's structures and blood flow without anything entering
the body. This information helps your doctor make an accurate
diagnosis and develop a treatment plan that's best for you. |

TEE (Transesophageal echocardiography) |
|
Transesophageal
echocardiography is a test that allows your doctor to record images
of your heart from inside your esophagus, or food pipe. Since the
esophagus lies just behind the heart, TEE may produce clearer
pictures of the heart's movement than would standard echocardiography
taken from outside the chest. During TEE, harmless sound waves bounce
(echo) off your heart. These sound waves create images of your heart
as it pumps blood throughout the valves of your heart as it pumps
blood throughout the valves and chambers. |

CAD (coronary artery disease) |
|
The heart receives
life-giving blood from vessels called coronary arteries. If these
arteries become partially blocked or narrowed by the accumulation of
fatty materials, the heart may not receive the blood it needs to
function properly. This narrowing of coronary arteries is called
coronary atherosclerosis or, more commonly, coronary artery disease
(CAD).
As CAD progresses, the heart muscle may not receive enough blood when
under stress, for example, when exercising. This often results in
chest pain called angina pectoris. On the other hand, there may be no
outward physical signs of the disease.
If CAD is limiting blood flow to a part of your heart, the stress
exam with CARDIOLITE may be useful in detection the presence and
significance of CAD.
This exam usually consists of two parts, rest and stress: |
|
--CARDIOLITE will be
administered by injection while you are at rest, and a special camera
will take pictures of your heart. |
|
--CARDIOLITE will be
administered to you one other time by an injection during exercise
(the "stress" portion of the test), and additional pictures will be
taken of your heart. |
|
This allows the physician to
compare the amount of blood flowing through the heart muscle during
stress and at rest. The pictures are generally taken about one-half
hour or later, after CARDIOLITE is administered. |
|
|
|
Stress EKG |
|
The stress EKG, or stress
test, conducted while you exercise on a treadmill or stationary
bicycle, measures your heart's health under the stress of physical
activity. Your blood pressure and pulse are also monitored by a
specially trained technician, an expert in using stress test
equipment. Results will be evaluated by a cardiologist or your
physician. The stress EKG aids in determining how fit you are and how
safe an exercise program is for you, or if a heart problem exists.
During the test a technician will place electrodes, or metal discs,
on your arms, shoulders, and chest. These electrodes are connected by
wires to the electrocardiograph machine. An EKG at rest will be taken
first. You will then step onto the treadmill or stationary bicycle
and exercise according to your doctor's instructions. Your blood
pressure and pulse are checked during and after the test. |
