Test Definitions

Electrocardiogram
Electrocardiogram (ECG or EKG) is a graphic record of the electrical activity of the heart as it contracts and rests. It can be used in the diagnosis of a number of heart conditions including valve disorders, arrhythmias, and heart attack.

Stress Test
A stress test is used to record the heartbeat during exercise. EKG and blood pressure readings are taken before, during, and after exercise to see how your heart responds to exercise. The exercise can involve walking on a treadmill, or pedaling a stationary bicycle, or you may receive medicine to make your heart beat faster. This test can be used in the diagnosis of heart disease.

Lung Function Tests Pulmonary function Testing
Lung function tests (or pulmonary function tests, PFT) evaluate how much air your lungs can hold, how quickly you can move air in and out of your lungs, and how well your lungs add oxygen to the blood and remove carbon dioxide from the blood. The tests can help diagnose lung diseases and measure the severity of lung problems that prevent you from breathing normally.

Arterial blood gases:
An arterial blood gas (ABG) test can measure the levels of two gases in the blood to determine how well the lungs are working. It evaluates the ability of the lungs to move oxygen into the blood and to remove carbon dioxide from the blood. As blood passes through the lungs, oxygen moves into the blood while carbon dioxide moves out of the blood into the airspace of the lungs.

Holter Monitor
A Holter monitor is a device worn by a patient for a continuous period of time (usually 24-48 hours) to provide an EKG recording of the heart's rhythm during the time it is worn. It can be used in the diagnosis of arrhythmias.

Event Monitor
An event monitor is a device used by a patient for a 30 day period, to provide an EKG recording of the heart's rhythm. It can be activated when the patient feels chest pain, dizziness or an irregular heartbeat coming on and can be used in the diagnosis of arrhythmias.
