An electrocardiogram (ECG) is a diagnostic test that is used to detect abnormalities in the heart's rhythm. It also can provide important information about damage to the heart, valve disorders, structural abnormalities in the heart's walls, and more. NewYork-Presbyterian Hospital provides the full range of advanced electrocardiography services, including:
Resting ECG. This test monitors the heart's activity at rest.
Exercise ECG. This test monitors the heart's activity under conditions of physical exercise. It is used for the evaluation of exercise capacity, for the detection of coronary disease and the assessment of its severity, for prediction of cardiovascular risk, and for monitoring the response to treatment.
Signal-averaged ECG. Performed for 15-20 minutes, information obtained from this test is processed by a computer to permit detection of cardiac abnormalities that might not be detected by standard ECG. Signal-averaged ECG is used when arrhythmia is suspected but not seen on a resting ECG, since arrhythmias may be transient in nature and not seen during the short recording time of the resting ECG.
Holter (Ambulatory) Monitoring. The Holter monitor is a portable electrocardiograph machine that allows readings to be made over a 24-hour period, while the individual is performing the usual activities of daily living at home or at work.
Event/loop Recording. Portable event/loop recorders can monitor heart activity for weeks to months, while the device is worn by the individual at home. A permanent record is kept only when the patient activates the recorder during periods when symptoms are felt.
