Cardiac Tests and Procedures

These tests and procedures are used to identify problems in the heart.

Cardiac Catheterization – Creates X-ray movies of the heart’s chambers, valves and major blood vessels

Cardioversion – A medical procedure of electric shocks to restore a normal heart rhythm

Catheter Ablation – Used to treat some types of arrhythmia. A series of thin, flexible wires are used to send energy to the heart.

Echocardiogram (Echo) – Outlines heart movements and provides pictures of the valves, chambers and pumping actionUltrasound

Electrocardiogram (EKG) – Records the electrical activity of the heart

Electroencephalogram (EEG) – Records the electrical activity of the brain

Electrophysiology Study – Tests that look at how well the heart’s electrical signals are working

Event Monitoring – Records EKG when activated by the patient

Holter Monitoring – Records EKG continuously for 24 hours

Pacemakers – Send small electrical impulses to the heart muscle to maintain a suitable heart rate or to stimulate the lower chambers of the heart

Stress Testing – Provides information about how the heart responds to stress or exercise

Pulmonary Tests and Procedures

These tests are used to identify problems in the lung.

Pulmonary Function Testing (PFT) – Records how well the lungs are working

PulmonaryBronchoscopy – Allows the physician to look into your lungs

Arterial Blood Gases (ABG) – Determines how much oxygen is in your blood

Breathing Treatment – Opens up the breathing tubes in your lungs and make it easier to breath

Sleep Disorder Testing – Identifies various sleeping problems so they can be treated

Vascular Tests and Procedures

These tests are used to identify problems in the blood vessels.

Carotid Doppler – A non-invasive test that uses sound waves to measure the flow of blood through the large carotid arteries that supply blood to the brain

Venous Doppler – This test uses ultrasound to examine the blood flow in the major arteries and veins in the arms and legs

Non-Invasive Arterial Studies (PVR) – Checks for good arterial blood flow and can assess the severity and location

Ankle Brachial Index (ABI’s) – Compares the blood pressure in your ankles to the blood pressures in your arms
