Diagnosis is easily made with an electrocardiogram.

 |
An electrocardiogram (ECG) is a test that records the electrical activity of the heart. See also: Holter monitoring; Stress test.
|
|
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...
|
|
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.
|
|
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 indi...

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with ha...

The health status of populations and of individuals is assessed for many reasons. Assessing needs for care helps guide the allocation of resources— diagnostic assessments guide treatment, prognostic assessments contribute to planning, and assessin...

Auscultation is the method of listening to the sounds of the body during a physical examination.
|
 |
A Holter monitor is a machine that continuously records the heart's rhythms. The monitor is usually worn for 24 - 48 hours during normal activity. See also ECG.
|
 |
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 th...

Intracardiac electrophysiology study (EPS) is an invasive test that allows doctors to determine the details of abnormal heartbeats, or arrhythmias. See also: Cardiac ablation procedures
|
|
An electrophysiology study (EPS) of the heart is a test performed to analyze the electrical activity of the heart. The test uses cardiac catheters and sophisticated computers to generate electrocardiogram (EKG) tracings and electrical measurements...

 |
An electrophysiology (EP) study of the heart is a nonsurgical analysis of the electrical conduction system (normal or abnormal) of the heart. The test employs cardiac catheters and sophisticated computers to generate electrocardiogram (EKG) tracin...

The multiple-gated acquisition (MUGA) scan is a non-invasive nuclear test that uses a radioactive isotope called technetium to evaluate the functioning of the heart's ventricles.
|
|
The multiple-gated acquisition (MUGA) scan , also called a cardiac blood pool study, is a non-invasive nuclear medicine test that displays the distribution of a radioactive tracer in the heart . The images of the heart are obtained at intervals th...

 |
An echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than a plain x-ray image and involves no radiation exposure.
|
 |
Echocardiography is a diagnostic test that uses ultrasound waves to create an image of the heart muscle. Ultrasound waves that rebound or echo off the heart can show the size, shape, and movement of the heart's valves and chambers as well as the f...
