cardiacecho2  Ultrasound Imaging

Is a method of obtaining pictures of structures inside the human body through the use of high frequency sound waves.The sonic signals are recorded and displayed as real-time visual images. We use the same machines that can be used to image babies in utero.These sound waves are totally harmless to the human body.

  Cardiac Ultrasound

Echocardiography is used to examine all structures of the heart, including both chambers and valves. Our color-flow Doppler ultrasound allows us to see the blood flowing within the heart, allowing us to see if the valves are too narrow or too loose, which are the usual causes of heart murmurs.  We can assess the vigor of contraction of the heart chambers, thus determining the presence of coronary heart disease(CHD and CAD) and heart attacks (myocardial infarctions, or MI’s), and other causes of heart failure (CHF).

 cardiacecho2  Soft Tissue Ultrasound

Images the organs within the abdomen, including the kidneys, liver, gallbladder, pancreas, spleen, and abdominal aorta (to check for aneurysm).  Our imaging can also be useful in evaluating superficial structures such as lumps and areas of discoloration.

Soft Tissue Ultrasound

 cardiacecho2  Vascular Ultrasound

Provides imaging of the arteries and veins.  The most common such studies are of the Carotid Arteries in the neck, as well as the blood vessels of the arms and legs, assessing for arteriosclerosis (“hardening of the arteries”, PAD) as well as blood clots and other disease states.

Electrocardiography and Basic Pulmonary Function Testing

 cardiacecho2  EKG

Also called ECG, or “heart wave test,” this electrical recording is a simple, painless, and harmless but extraordinarily valuable technique for recording the heart’s rate, rhythm and arrhythmias, electrical axis, and time intervals.  Because it is relatively inexpensive and harmless, this test can be repeated many times over the years to document changes in these important measures of cardiac function.

Holter Monitoring

 Also called Ambulatory Electrocardiography, is a recording of the heart rhythm for 24 hours or longer. This test is exceedingly valuable in the assessment of palpitations, dizzy spells, fainting spells (syncope), or in detecting arrhythmias such as atrial fibrillation.


 cardiacecho2  Simple Spirometry

Is a test that measures respiratory function (health of the lungs). This test is vital in assessing symptoms of shortness of breath or poor exercise tolerance.  Spirometry can be essential in diagnosing asthma, bronchitis, and emphysema (COPD).
