Barnabus Health Medical Group in Lyndhurst, NJ


Dr. Sheila Nadiminti is a board-certified cardiologist at United Medical. She sees patients in two of our offices: Lyndhurst and Clifton, New Jersey. Dr. Nadiminti has special training and knowledge to identify symptoms of heart disease, such as chest pain, shortness of breath, hypertension, and high cholesterol.

Common cardiology conditions include:

Diagnosing Heart Problems

Using advanced cardiac imaging technology, we can perform an in-office EKG and do blood work to evaluate the health of your heart. If there is an abnormality, Dr. Nadiminti may order additional testing to diagnose a heart condition. We do echocardiograms, electrocardiograms, and a wide range of cardiac stress tests in our New Jersey offices.

ICAEL Accredited Laboratory

United Medical has been granted accreditation in the area of adult transthoracic by the Intersocietal Commission for the Accreditation of Echocardiography Laboratories (ICAEL) in all three of its locations: Lyndhurst, Clifton, and Bayonne, New Jersey.

Accreditation by the ICAEL means that United Medical PC has undergone a thorough review of its operational and technical components by a panel of experts.

The ICAEL grants accreditation only to those facilities that are found to be providing quality patient care. ICAEL is a "seal of approval" that patients can rely on as an indication that the facility has been carefully critiqued on all aspects of its operations in the field of echocardiography. Patients should remain vigilant in making sure that their echocardiography procedures are performed within accredited laboratories, because for many facilities it remains a voluntary process.


An echocardiogram is a painless test that uses ultrasound imaging to create pictures of your heart. The test gives your doctor information about the size and shape of your heart and how well your heart's chambers and valves are working. The test can also identify areas of heart muscle that are not contracting normally due to poor blood flow or injury from a previous heart attack. An echocardiogram can detect possible blood clots inside the heart, fluid buildup in the pericardium, and problems with the aorta.

Echocardiogram uses sound waves to create a moving picture of the heart. The picture is much more detailed than a plain X-ray image and involves no radiation exposure. Occasionally, your lungs, ribs, or body tissue may prevent the sound waves and echoes from providing a clear picture of heart function. If so, the sonographer may inject a small amount of liquid (contrast) through an IV to better see the inside of the heart.

Our doctors may perform an echocardiogram to diagnose, evaluate, and monitor:

  • Heart murmurs
  • Abnormal heart valves
  • Pumping function of the heart for people with heart failure
  • Damage to the heart muscle in patients who have had heart attacks
  • Infection in the sac around the heart (pericarditis)
  • Infection on or around the heart valves (infectious endocarditis)
  • The source of a blood clot or emboli after a stroke or TIA (transient ischemic attack)
  • Congenital heart disease
  • Atrial fibrillation
  • Pulmonary hypertension

Types of Echocardiograms

There are several types of echocardiograms. Our heart doctor will determine which is appropriate for you.

Transthoracic Echocardiogram

This is the standard echocardiogram. The procedure uses the same technology used to evaluate a baby's health before birth. A hand-held device called a transducer is placed on the chest and transmits high frequency sound waves (ultrasound). These sound waves bounce off the heart structures, producing images and sounds that can be used by the doctor to detect heart damage and disease.

Transesophageal Echocardiogram (TEE)

This test requires that the transducer be inserted down the throat into the esophagus. Because the esophagus is located close to the heart, clear images of the heart structures can be obtained without the interference of the lungs and chest.

Stress Echocardiogram

This is an echocardiogram that is performed while a patient 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 to and after exercise.

Dobutamine or Adenosine/Sestamibi 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), as well as evaluating the effectiveness of your cardiac treatment plan.


An electrocardiogram (EKG or ECG) is a non-invasive test that is used to reflect underlying heart conditions by measuring the electrical activity of the heart. By positioning leads (electrical sensing devices) on the body in standardized locations, information can be learned about many heart conditions by looking for characteristic patterns on the EKG.

An EKG is usually performed as part of a routine physical examination. Your doctor may order this test if you have chest pain, shortness of breath, fainting, or palpitations. An EKG is a very useful preoperative workup for surgery in patients who may be at an age where heart disease could potentially be present.

An electrocardiogram can detect:

  • The underlying rate and rhythm mechanism of the heart
  • The orientation of the heart (how it is placed) in the chest cavity
  • Increased thickness (hypertrophy) of the heart muscle
  • Possible damage to various parts of the heart muscle
  • Evidence of acutely impaired blood flow to the heart muscle
  • Patterns of abnormal electric activity that may predispose the patient to abnormal cardiac rhythm disturbances

The test takes about five minutes. It is painless and no electricity is sent through the body. In some instances, we may need to shave a small amount of a man’s chest hair to obtain optimal contact between the leads and the skin.

Stress Test

A stress test, also called an exercise stress test, is used to gather information about how well your heart works during physical activity. Because exercise makes your heart pump harder and faster than it does during most daily activities, an exercise stress test can reveal problems within your heart that might not be noticeable otherwise.

An exercise stress test usually involves walking on a treadmill or riding a stationary bike while your heart rhythm, blood pressure, and breathing are monitored.

Our doctors may recommend a stress test if he or she suspects you have coronary artery disease or an irregular heart rhythm (arrhythmia). The test may also be used to guide your treatment if you've already been diagnosed with a heart condition, as well as to:

  • Evaluate exercise tolerance when patients have unexplained fatigue and shortness of breath
  • Evaluate blood pressure response to exercise in patients with borderline hypertension
  • Look for exercise-induced serious irregular heart beats

Types of Stress Tests

Treadmill Stress Test

As long as you can walk and have a normal ECG, this is normally the first stress test performed. You walk on a treadmill while being monitored to see how far you walk. If you develop any chest pain or changes in your ECG, this suggests that your heart is not getting enough blood.

Stress Echocardiogram

A cardiac stress test, or stress echocardiogram, is a graphic outline of the heart's movement. A stress echo can accurately 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.

Dobutamine or Adenosine/Sestamibi Stress Echocardiogram

This is another form of stress echocardiogram for people who are unable to exercise. A drug is given to make the heart respond as if the person were exercising. This way the doctor can still determine how the heart responds to stress, but no exercise is required.

Nuclear Stress Test

A nuclear stress test helps to determine which parts of the heart are healthy and function normally and which are not. A small amount of radioactive substance is injected into the patient. The doctor uses a special camera to identify the rays emitted from the substance within the body, which produces clear pictures of the heart tissue on a monitor.

These pictures are obtained both at rest and after exercise. Using this technique, a less than normal amount of thallium will be seen in those areas of the heart that have a decreased blood supply.

Treating Heart Conditions

Many patients respond well to medication and lifestyle changes to treat common problems with blood pressure, cholesterol, and clogged arteries. For more serious problems where an artery, vein, or valve is diseased or damaged, the use of a stent or other interventional cardiology procedure may be necessary. If you need an interventional procedure, our cardiologist can refer you to a specialist who does them.

Diagnosis and Treatment of Heart Disease in New Jersey

You should discuss any concerns you have about your heart health with your primary doctor, who can refer you to a cardiologist like Dr. Nadiminti for further evaluation. If you have a history of heart trouble in your family, or if you have certain risk factors (smoking, overweight, sedentary lifestyle, high stress level), do not hesitate to seek the advice of a cardiologist.
