Non-Invasive Cardiology Services

An electrophysiology study (EPS) is like a deep dive into the intricate wiring of your heart. It’s a specialized test that allows us to assess the health and functionality of your heart’s electrical system. 

An echocardiogram stress test, often referred to as a heart stress test, is like a dynamic performance review for your heart. It’s a specialized examination that allows us to witness how your heart muscle responds to exercise compared to its resting state. 

A Holter monitor is like a loyal companion for your heart, always on watch to detect and record any irregularities in your heart rhythm. It’s a small but powerful device that plays a crucial role in assessing your heart’s health, especially when you’re experiencing symptoms like chest pain or palpitations. 

Electrical cardioversion is like a reset button for your heart when it’s dancing to an irregular beat. It’s a safe and effective procedure used to restore a normal heart rhythm in individuals experiencing arrhythmias or irregular heartbeats. 

Cardiac catheterization is like a guided tour of your heart’s inner workings, a journey that allows us to explore, diagnose, and sometimes even treat various heart conditions. It’s a remarkable procedure that offers critical insights into your heart’s health.

The 64 slice CT angiogram is like a high-definition camera for your arteries, offering unprecedented clarity and precision in the diagnosis of arterial blockages. It’s a cutting-edge imaging technique that revolutionizes the way we assess your vascular health.


Wired & Wireless Event Monitoring

Event monitoring, whether wired or wireless, is like having a vigilant guardian for your heart’s rhythm. It’s a specialized service that allows us to continuously track your heart’s electrical activity, capturing valuable data to diagnose and manage heart rhythm disorders.


A transthoracic echocardiogram (TTE) is like a magical window into your heart’s inner workings, creating a captivating visual symphony of your heart’s movements. This noninvasive procedure is a go-to choice for gaining valuable insights into your heart’s health.


Anticoagulation monitoring is like having a vigilant guardian for your blood, ensuring it flows smoothly and coagulates appropriately. This essential service is designed to keep a close watch on the effects of anticoagulant medications, which prevent blood clot formation.

Pacemaker & Defibrillator Monitoring

Portable heart rhythm monitoring is like having a silent guardian for your heart, always vigilant and ready to record its every beat. This ingenious device offers continuous surveillance, helping us detect arrhythmias and other heart conditions that may go unnoticed.

Imagine a captivating collaboration between an EKG machine and a CT scanner, where electrode pads delicately placed on your chest and the keen eye of the CT scanner work in unison to unveil the intricate tale of your heart’s electrical rhythm while capturing strategic snapshots of your chest. This ingenious partnership brings together the science of electrocardiography (EKG) and the art of imaging, offering a holistic view of your heart’s inner workings.

Picture a dynamic assessment where your heart takes center stage, responding to exertion like a seasoned performer. This performance, known as the Stress ECG Test, goes by many names – exercise electrocardiogram, treadmill test, graded exercise test – but its purpose remains the same: to reveal how your heart behaves under the spotlight of physical activity.

The Carotid Duplex Ultrasound is a refined imaging procedure designed to meticulously assess the condition of your carotid arteries. These essential blood vessels in your neck play a critical role in supplying blood to your brain. This procedure employs high-frequency sound waves, known as ultrasound, to provide a detailed visualization of the carotid arteries, aiding in the detection of narrowing and potential blockages.


Transesophageal Echocardiography (TEE)

The Transesophageal Echocardiogram, often abbreviated as TEE, is a highly precise diagnostic procedure that utilizes echocardiography to capture detailed images of your heart and arteries. This advanced imaging technique is instrumental in evaluating cardiac function and assessing the overall performance of the heart.

The Ankle-Brachial Index (ABI) test stands as a straightforward yet insightful method employed by healthcare professionals to gauge the efficiency of blood flow throughout your body. This non-invasive procedure provides valuable insights into the circulatory health of your extremities, aiding in the assessment of potential vascular issues.

The realm of peripheral vascular tests serves as a crucial investigative tool, shedding light on the presence of significant blood clots within a patient’s arteries or veins. These tests, carefully designed to explore the intricate pathways of our circulatory system, hold paramount importance in the evaluation of vascular health.

The T-Wave Alternans test, a diagnostic procedure designed to provide profound insights into cardiac health, calls for a strategic approach. Similar to a stress test, it requires the temporary elevation of your heart rate to unveil essential cardiac patterns. The procedure involves the precise application of electrodes to your chest and back, connected to a specialized T-Wave Alternans machine through a wire.

Metabolic tests, a diagnostic approach that delves into the intricate world of caloric combustion, play a pivotal role in the assessment of metabolic health. These tests are instrumental in measuring the rate at which your body burns calories, thereby enabling healthcare professionals to identify subtle indications of metabolic imbalances.

The echocardiogram, a vital diagnostic tool embraced by physicians and cardiologists, unfolds as a masterpiece of medical imaging. This technique harnesses the power of sound waves to craft intricate images of the heart, providing invaluable insights into cardiac health.
