NON-INVASIVE CARDIAC PROCEDURES
What is an echocardiogram?
Another name for cardiac ultrasound is transthoracic echocardiogram. This is a noninvasive test that provides moving pictures of your heart in order to help the physician better visualize the pumping power, structure, and valves of the heart. A cardiac ultrasound uses the same technology that allows physicians to see an unborn baby inside a pregnant mother.
Echo can be used as part of a stress test and with an electrocardiogram. (EKG or ECG) to help your doctor learn more about your heart.
How do I prepare?
Please wear loose clothing, preferably two pieces, as you will be kindly asked to remove all clothing covering your chest. A patient gown will be provided for you during the test. This test is simple, noninvasive, and quick. It generally will not include any complications or require any recovery time. As soon as the ultrasound is done, you can return to your normal activities.
Exercise Stress Test
Why is an exercise test sometimes needed for assessing a valve problem?
Also called a stress test or treadmill test, exercise testing can provide valuable information in patients with valvular heart disease, especially in those whose symptoms may be difficult to assess. It has a proven track record of safety, even among symptomatic patients with severe aortic stenosis. Your healthcare provider may use an exercise test in combination with echocardiography, an angiogram and cardiac catheterization.
Exercise testing helps evaluate changes in blood pressure, changes in symptoms, and the heart’s response to a more challenging workload. If you have a heart murmur, your healthcare provider will take note of any changes in the murmur that happen during exercise. Read more about exercise testing.

Exercise Stress Testing
What is an exercise stress test?
Stress testing is a test that exerts the heart to determine how strong it is and whether it has any irregular heartbeats or blockages in the coronary arteries. Stress testing can be done using different methods depending on your physical capacity and medical history.
An exercise stress test, also known as a treadmill test, helps your doctor assess how well your heart responds to stress. It involves walking on a treadmill while your electrocardiogram, blood pressure and heart rate are being monitored. Depending on your medical indication, an ultrasound of the heart may also be done immediately following the completion of the exercise stress test in order to obtain images of your heart immediately after stress.
How do I prepare?
Arrhythmia is a condition where the heart beats too slow, too fast or irregularly. We offer various tests to look for heart rhythm disorder.
What is a Holter Monitor test?
A Holter monitor is a test that will record the electrical activities of your heart for 24 hours or more. During the duration of the test, you are allowed to continue with your usual activities including walking, eating, sleeping, etc.
How do I prepare?
Please shower before the test and wear loose clothing, preferably two pieces, the day of your test. This test is simple and noninvasive. It generally will not include any complications or require any recovery time.
Event monitors are small, portable electrocardiogram devices that record your heart’s electrical activity for long periods of time while you do your normal activities. These monitors can record how fast your heart is beating, whether the rhythm of your heartbeats is steady or irregular, and the strength and timing of the electrical impulses passing through each part of your heart. Information from these recordings helps doctors diagnose an arrhythmia, or irregular heartbeat, and check whether treatments for the irregular heartbeat are working.
There are many types of monitors, such as episodic monitors, autodetect recorders, 30-day event recorders, and transtelephonic event monitors. Your doctor will decide which monitor is best for you. Most monitors have electrodes with sticky adhesive patches that attach to the skin on your chest. Some monitors and electrodes used for long-term recording may be implanted under your skin to make it easier for you to bathe and perform your daily activities. Your doctor will explain how to wear and use the monitor and tell you whether you need to adjust your activity during the testing period. You should avoid magnets, metal detectors, microwave ovens, electric blankets, electric toothbrushes, and electric razors while using your monitor. Usually, you will be instructed to keep electronic devices such as cell phones, MP3 players, and tablets away from the monitor. After you are finished using the monitor, you will return it to your doctor’s office or the place where you picked it up. If you were using an implantable recorder, your doctor will remove it from your chest.
Also known as ambulatory EKG; continuous EKG; EKG event monitors.
Signal Averaged Electrocardiogram
What the test does?
An electrocardiogram (ECG or EKG) is one of the simplest and fastest procedures used to evaluate the heart. Electrodes (small, plastic patches) are placed at certain locations on the chest, arms, and legs. When the electrodes are connected to an ECG machine by lead wires, the electrical activity of the heart is measured, interpreted, and printed out for the doctor's information and further interpretation.
A signal-averaged electrocardiogram is a more detailed type of ECG. During this procedure, multiple ECG tracings are obtained over a period of approximately 20 minutes evaluating several hundred cardiac cycles to detect subtle abnormalities that increase risk for cardiac arrhythmias. These subtle abnormalities are usually not detected on a plain ECG. A computer captures all the electrical signals from the heart and averages them to provide the doctor more detail regarding how the heart’s electrical conduction system is working.
Signal-averaged ECG is one of several procedures used to assess the potential for dysrhythmias or arrhythmias (irregular heart rhythms) in certain medical situations.
Why have the procedure?
Reasons your doctor may request a signal-averaged ECG may include, but are not limited to, the following:
There may be other reasons for your doctor to recommend a signal-averaged ECG.

Pacemaker and Defibrillator Clinic
What is a pacemaker?
A pacemaker is a small-battery operated device that helps your heart beat regularly. Some pacemakers are surgically implanted and permanent. Other pacemakers are external and temporary.
What is an Implantable Cardioverter Defibrillator (ICD)?
An implantable cardioverter defibrillator (ICD) is a small-battery operated device that provides an electric shock to your heart to stop any life-threatening arrhythmia.

Cholesterol Reduction Program
Your doctor will work with you to understand your risk and then recommend the most suitable approach, including the advantages and disadvantages of treatment with statins. Factors to consider with your doctor include a family history of premature heart attack or stroke and an LDL cholesterol level of 160 mg/dL or higher. Your doctor may also suggest a high sensitivity C reactive protein inflammation test or a coronary artery calcium score, which can help determine your risk.
DAY-TO-DAY CHOICES MATTER
A healthy diet and exercise are vital to fend off high cholesterol and heart disease. Risk reduction begins with knowing your lifestyle habits.
Get active, eat better, lose weight, stop smoking, control cholesterol, manage blood pressure and reduce blood sugar.
Know your numbers, but treat your risk
A constellation of "numbers" is used to determine one’s personal risk of heart attack and stroke. The American Heart Association recommends that everyone know where they stand with the following four measurements. Ideal numbers for most adults are:
High cholesterol may cause serious heart disease to develop. It’s important to have your cholesterol levels monitored because, in most cases, high cholesterol doesn’t have any symptoms.
Cardiac Perfusion Scan
What is this test?
A cardiac perfusion scan measures the amount of blood in your heart muscle at rest and during exercise. It is often done to find out what may be causing chest pain. It may be done after a heart attackClick here to see more information. to see if areas of the heart are not getting enough blood or to find out how much heart muscle has been damaged from the heart attack.
What is the procedure?
During the scan, a camera takes pictures of the heart after a special test medicine (radioactive tracerClick here to see more information.) is given through an IVClick here to see more information.. The tracer travels through the blood and into the heart muscle. As the tracer moves through the heart muscle, areas that have good blood flow absorb the tracer. Areas that do not absorb tracer may not be getting enough blood or may have been damaged by a heart attack.
Two sets of pictures may be made during a cardiac perfusion scan. One set is taken while you are resting. Another set is taken after your heart has been stressed, either by exercise or after you have been given a medicine. The resting pictures are then compared with the stress images.
This test is also known by other names including myocardial perfusion scan, myocardial perfusion imaging, thallium scan, sestamibi cardiac scan, and nuclear stress test.
