Non-Invasive Testing

Lown Group welcomes both members and non‑members for testing

Ambulatory Blood Pressure Monitor

Ambulatory blood pressure monitoring is a non‑invasive test that measures your blood pressure over a 24‑hour period while you go about your normal day and sleep at night. It is worn on the upper arm, similar to the cuffs that we use to measure your blood pressure in our office, but a bit smaller. It will automatically inflate and deflate throughout the monitoring period.

Basal Metabolic Rate (BMR)

This test measures how many calories your body burns in the resting state. When you are active, you will burn more calories than the BMR.

Cardiac Ultrasound (Echocardiogram)

The “echo” is an imaging technique that bounces sound waves through the chest to provide a two-dimensional image of the heart muscle, valves, and other cardiovascular structures. This test also provides important information about the pressure inside the heart and lungs. Heart muscle function is evaluated periodically to monitor changes over the years and to guide medical therapy. In patients who have sustained a heart attack, an echo helps assess how the heart is healing.

Cardiopulmonary Stress Test (CPET)

A CPET is a stress test that includes the addition of pulmonary measurements. This is achieved by wearing a mouthpiece that collects breath-by-breath measurements of inhaled oxygen and exhaled carbon dioxide. A baseline pulmonary capacity test is performed on every athlete before starting exercise. Analyzing both cardiac and pulmonary function allows us to determine the source of any problems. We can also use this test to determine the anaerobic threshold and maximal oxygen consumption for athletes looking to enhance performance.

Defibrillator and Pacemaker Evaluations

Exclusive offering for our members

Many of our patients have implanted pacemakers, defibrillators, or automatic internal cardiac defibrillators (ICDs).

Our Lown cardiologists provide evaluations and monitoring for these devices, including telephonic surveillance.


Multiple clinical trials support the use of implantable cardioverter-defibrillators (ICDs) for the prevention of sudden cardiac death in patients with heart failure (HF).

Exercise Tolerance Test (ETT)

Stress tests check for abnormal blood flow to the heart due to blocked heart arteries and evaluate the heart’s response to exercise. The most common type of stress test involves walking on a treadmill to increase heart rate and blood pressure. Stress tests provide information that may not be apparent on a resting electrocardiogram. Results of a stress test may help explain symptoms that you have reported to your physician.

Heart Rhythm Monitoring

(Including MCT, Holter Monitoring, and Event Monitors)

Exclusive offering for our members

These monitors provide advanced, remote, cardiac monitoring designed to provide continuous, high-quality heart health data—no matter where you are.


Monitors are tailored for patients who need ongoing monitoring, whether at home or on the go, and offers a comfortable, discreet experience. These are typically lightweight, wearable sensors, continuously tracking your heart's rhythm, detecting potential issues like arrhythmias (irregular heartbeats), and sending real-time data to your healthcare team. This means your doctor can monitor your heart health remotely and intervene quickly if needed.

InBody Scan

Exclusive offering for our members

An InBody scan uses multi-frequency bioelectrical impedance analysis to measure body composition including fat mass, fat-free mass skeletal muscle mass, body water and body fat percentage.

Stress Echocardiogram (STE)

The stress echo combines the exercise tolerance test with an ultrasound of the heart, performed before and after exercise. This test looks at the squeezing function of the heart before and after exercise, which is an indication of blood flow. Normally, the heart function becomes stronger after exercise, however if there are blockages in the heart arteries, the muscle may become weaker.

Vascular Ultrasound

This test uses ultrasound to evaluate blood flow in the arteries and veins of the body. Vascular testing is performed in our office by Registered Vascular Technologists using state-of-the-art high frequency ultrasound equipment.

We offer the following types of vascular ultrasound:



  • Carotid artery - this test assesses blood flow through the carotid arteries in the neck, which supply blood to the brain. Narrowings of the carotid artery can increase the risk for stroke.
  • Upper extremity arteries - this test assesses for narrowing or blockage of the arteries that supply blood to the arms. 
  • Abdominal aorta - we use this study to look for enlargement ("aneurysm") , narrowing, or significant plaque buildup of the abdominal aorta.
  • Lower extremity arteries - this test is used to check for narrowings in the arteries that bring blood to the legs. We usually use this test to assess for peripheral arterial disease ("PAD"), or insufficient blood supply to the legs, which can cause muscle cramps during exercise.
  • Renal (kidney) arteries - this test is used to look for narrowing in the arteries that bring blood to the kidneys. We usually use this test to help in the assessment of someone with unexplained or difficult to control high blood pressure.
  • Lower extremity veins ("LENIs") -this test is used to look for blood clots in the legs ("deep vein thrombosis", or "DVT") or to assess for weakness and reflux in the leg veins
