View the services below to learn more about our diagnostic procedures. Basic Testing Electrocardiogram (EKG) – An EKG records the electrical signals that control the rhythm of your heartbeat. EKGs are used to diagnose a wide range of heart problems from arrhythmia to coronary heart disease. Holter Monitor – The Holter monitor records electrical signals of the heart just like an EKG, but it does so over a 24-hour period. This test will monitor your heart rhythm as you perform regular daily activities to see how your heart responds to changes in activity, rest and medication. Treadmill Stress Test – We use the treadmill as an exercise test to evaluate your heart function as well as how your pulse and blood pressure respond to physical activity. Cardiopulmonary Exercise Test (CPET) – A CPET is used to evaluate the function of your lungs, heart and muscles at rest and during exercise. Ankle Brachial Index (ABI) Screening – An ABI screening is a simple, painless test used to determine blood flow in the legs. Bloodwork – Bloodwork is a very important part of diagnosing and monitoring certain medical problems. Results from bloodwork can help the physician determine which organs may need treatment, or if levels in your blood need medication to be regulated.
