Diagnostic Procedure
MEDOP 230- Cardiology: Diagnostic Procedures
Term | Definition | Note |
---|---|---|
Cardiac catheterization | Procedure to study anatomy and pressures in the heart | •A catheter is inserted into the femoral or brachial vein and threaded to either side of the heart. |
Right heart catheterization | measures pressures in the right atrium and ventricle and pulmonary artery. | |
Left heart catheterization | involves use of contrast dye to show blockages in the coronary arteries. | |
Cardiac exercise stress test | Procedure to evaluate the heart’s response to exercise in patients with chest pain, palpitations, or arrhythmias. | •Patient walks on a treadmill while an ECG is performed.•If necessary, patients may instead ride a stationary bike or undergo a pharmacologic stress test. |
Electrocardiography (ECG, EKG) | Procedure that records the electrical activity of the heart. | •Electrodes are placed on the limbs and chest and used to show activity from 12 angles.•Tracings of each pattern are used to create an electrocardiogram. |
Electrophysiologystudy (EPS) | Procedure that maps the heart’s conduction system to find an ectopic site causing arrhythmia. | •While an ECG is performed, catheters are inserted into veins and guided to the heart.•The catheters send out impulses to stimulate the heart and locate the ectopic site. |
Holter monitor | Procedure to document infrequent arrhythmias | involves use of a portable ECG monitor to continuously track a patient’s heart rate and rhythm for 24 hours. |
Telemetry | Procedure to monitor a patient’s heart rate and rhythm in the hospital | .•The patient wears electrodes that transmit ECG tracings to a central monitoring station.•A nurse at the station watches multiple patients’ tracings simultaneously. |
