Cardiovascular Conditions & Disease

Non-Invasive Cardiology Services

An electrophysiology study is used to test the health of your hearts electrical system.

An echocardiogram stress test, also called a heart stress test, is used to see how an individual’s heart muscle contracts while exercising compared to while at rest.

A Holter monitor is used to detect any abnormal heart rhythm and to evaluate the patient’s EKG during episodes of chest pain and other symptoms.

An electrical cardioversion is used to return a heart with an arrhthmia back to a normal rhythm. An electrical shock is transmitted to the patient via patches or paddles on the outside of the chest.

Cardiac catheterization is a procedure involving a thin, hollow tube called a catheter which is to examine your heart for various conditions.

The 64 slice CT Angiogram uses computed tomography to produce extremely clear images, without the use of catheters or dyes, to determine blockage of arteries.


Wired & Wireless Event Monitoring


A transthoracic echocardiogram (TTE) uses ultrasound to produce high quality moving imagery. It is an extremely popular noninvasive procedure.

Pacemaker-&-Defibrillator-Monitoring in Long Island

Pacemaker & Defibrillator Monitoring

A portable device continuously monitors heart rhythm and records the heart’s activity to determine if an arrhythmia or other condition is present.

By placing electrode pads on your chest while also being connected to a CT scanner, an EKG machine about the electrical activity of the heart while the CT scanner will take strategic photos of the chest. 

This stress test — also called a exercise electrocardiogram, treadmill test, graded exercise test or stress ECG — is used to provide information about how the heart responds to exertion. 

A carotid duplex ultrasound is an imaging procedure that uses high-frequency sound waves to view the carotid arteries and to determine the presence of narrowing.


Transesophageal Echocardiography (TEE)

A transesophageal echocardiogram (TEE) uses echocardiography to take pictures of your heart and arteries and assess how well the heart works.

An ankle-brachial index (ABI) test is a simple way for your doctor to check how well your blood is flowing.

Peripheral Vascular tests are used to investigate whether or not there are any significant blood clots in a patient’s arteries or veins.

The test is performed using a treadmill (like a stress test) because it’s necessary that the heart rate be raised for a short time. We apply electrodes to your chest and back that connect to a wire that leading to the T-Wave Alternans machine.

Metabolic tests measure the rate at which your body burns calories, enabling doctors to identify indications of a metabolic imbalance.

An echocardiogram is used by physicians and cardiologists to produce images of the heart with the use of sound waves.
