An EKG is a noninvasive test that is usually performed in the doctor’s office or hospital which involves placing several electrode patches on the chest and extremities. It is used to record the electrical signals of the heart.
A Holter monitor is a specialized wearable outpatient heart monitor that is attached to the skin via electrode patches and records electrical signals of the heart. It is usually worn for 1 to 2 days to diagnosis arrhythmias.
An event monitor is specialized wearable outpatient heart monitor (like a Holter monitor) that is attached to the skin via electrode patches and records electrical signals of the heart. It can be worn for up to 1 month and records events of arrhythmia if they occur or can be triggered by the patient if they feel symptoms.
An echocardiogram is a specialized ultrasound test that is used to examine the structure and function of the heart. It can be used to study the heart chambers, valves, and structures around the heart.
A stress test is a type of heart examination study where you gather information on the heart when it is stressed. The stress can be done by physical activity on a treadmill or bicycle, or with medications all while your heart rate, heart rhythm, blood pressures, and symptoms are being monitored. Then using EKG and/or an imaging study, the heart response with the stress is determined.
A cardiac catheterization is a specialized invasive test performed by cardiologists by inserting catheters into the heart. This test is often performed to record pressures in the heart and examine for blockages in the arteries that supply the heart muscle (i.e. coronary arteries).
