The Basic Facts of EKG Tests
An electrocardiogram is also known as an EKG or an ECG in medical terminology. In simple terms, it is a harmless and pain-free test that measures and records heart rhythm. It can detect electrical activity, as it passes through the various parts of the heart and it can record both regular and irregular heartbeats. Once the heart rate is detected it can be displayed on either a monitor or on graph paper that the physician can read and interpret for the patient.
An EKG machine detects heart activity through electrodes that are placed on the bare skin of a patient. It takes about minutes to perform the test. EKG machines can assist doctors in revealing a variety of health problems such as:
· rapid heart beat
· abnormally decreased heart beat
· irregular pumping of the heart
· abnormal heart muscle size
· heart birth defects
· the presence of heart disease located in the heart valves
· heart attack (past or present)
Doctors might recommend that a patient have an EKG test done either as a tool for diagnosing for screening the early warning signs of heart disease, or to determine the source of a patient’s symptoms. When no symptoms are present, doctors typically only order EKG tests for patients that have a family history of heart disease in their immediate family. Some common symptoms that would cause a physician to order the test are:
· breathing problems
· chest pain
· fatigue
· uneven heart beat
· abnormal heart sounds
Lastly, EKG tests can also be used by doctors to monitor the effectiveness of heart treatments, such as medical devices or medications. Special EKG machines can be utilized so that doctors are able to monitor the heart rate of a patient over longer periods of time. These EKG machines are portable and can be worn by the patient throughout the day.
