The health care provider may hear a fast heartbeat while listening to the heart with a stethoscope. The pulse may feel rapid, irregular, or both. The normal heart rate is 60 - 100, but in atrial fibrillation/flutter the heart rate may be 100 - 175...

A doctor can sometimes hear these arrhythmias using an instrument (a stethoscope) to listen to the sounds within the chest. Atrial fibrillation and flutter are usually diagnosed through electrocardiography (EKGs), an exercisestress test , a 24-hou...

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...

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 exercise stress test is a screening tool to test the effect of exercise on your heart. It provides an overall look at the health of your heart. See also: Stress echocardiography; Thallium stress test.
|
|
Used to evaluate heart function, a stress test requires that a patient exercises on a treadmill or exercise bicycle while his or her heart rate, breathing, blood pressure, electrocardiogram (ECG), and feeling of well being are monitored.
|
|
|
A stress test is primarily used to identify coronary artery disease. It requires patients to exercise on a treadmill or exercise bicycle while their heart rate, blood pressure, electrocardiogram (ECG), and symptoms are monitored.

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...
