 |
An electrocardiogram(ECG) is a test that records the electrical activity of the heart.
|
|
Electrocardiography is a commonly used, noninvasive procedure for recording electrical changes in the heart. The record, which is called an electrocardiogram(ECG or EKG), shows the series of waves that relate to the electrical impulses that occur ...

Detailed information on electrocardiogram, including how the EKG/ECG is performed and what happens after the procedure
|
 |
The electrocardiography unit, also called an electrocardiograph, is an apparatus that indirectly measures the heart''s electrical activity and records it as a graphic tracing.Electrocardiography is used to detect heart-function abnormalities. It in...

Did you know that electrical currents flow throughout your body? Because the strongest of these travels through your heart, doctors are able to monitor your heart by placing electrical sensors on the surface of your skin.
|
|
The ECG (also known as EKG) is a test that records electrical signals from your heart onto a paper strip. The pattern of these signals can tell the doctor whether your heart is normal, under stress, or experiencing electrical problems, strain, or damage.
|
|
The electrocardiogram(ECG) displays important information about the heart, including the occurrence of a heart attack or lack of oxygen, whether conduction of the heartbeat is disturbed, or its rate or rhythm altered. It is useful as a rapid indic...

During a physical examination, a health care provider studies a patient''s body to determine the presence or absence of physical problems.
|
 |
Auscultation is the method of listening to the sounds of the body during a physical examination.Auscultation is usually done using a tool called a stethoscope. Health care providers routinely listen to a patient''s lungs, heart, and intestines to e...

 |
Holter monitoring is continuous monitoring of the electrical activity of a patient''s heart muscle( electrocardiography) for 24 hours, using a special portable device called a Holter monitor. Patients wear the Holter monitor while carrying out thei...

Detailed information on Holter or event monitoring When symptoms such as dizziness, fainting, low blood pressure, prolonged fatigue, or palpitations continue to occur without a definitive diagnosis obtained with a resting electrocardiogram (ECG), your child's physician may request an ECG tracing to be run over a long period of time. Certain arrhythmias (a fast, slow, or irregular heartbeat) which can cause the symptoms noted above may occur only sporadically, or may occur only under certain conditions, such as stress. Arrhythmias of this type are difficult to obtain on an ECG tracing that only runs for a few minutes.

|
Holter monitoring is a painless way to record your heartbeat away from the doctor's office. It is a small electrocardiogram (ECG) that you carry with you. Holter monitoring records your heartbeat for your doctor to review at a later time.
