An EKG can show you the electrical activity of your heart. The activity of your heart is recorded as peaks and dips on a grid background. These peaks and dips are recorded as lines and these lines are called waves. The heart is made of four different chambers, two on the top and two on the bottom. The contraction of these chambers is what pumps the blood, these contractions are guided by electrical signals.
EKG is used for
Check the heart’s electrical activity.

Find the cause of unexplained chest pain or pressure.
Can be caused by a heart attack, inflammation, or angina.

Find the cause of symptoms of heart disease.
Symptoms include shortness of breath, dizziness, fainting,
————and rapid/irregular heartbeats.

Find out if the walls of the heart chambers are too thick.

Measure the effectiveness of medications and side effects that affect the heart.

Check how well mechanical devices that are implanted in the heart.
Such as pacemakers, are working. These devices help to control the heartbeat.

Check the health of the heart when other diseases or conditions are present.
These include high blood pressure, high cholesterol, cigarette smoking, diabetes and heredity of heart disease.

EKG Procedure:

During an EKG, some spots of your arms, legs and chest will be shaved and cleaned for the attachment of electrodes. Severe electrodes are attached to the previously cleaned area. These electrodes are connected with a heart monitor machine that traces the heart’s activity onto a paper.

An EKG test is completely safe, there are no reason why you should not be able to get one.

EKG is not one hundred percent accurate, there are times the heart activity appear to be normal when in-fact its not. Because of this reason, EKG is view together with the patients symptoms, past health, and a physical exam.

Sometimes analyzing EKG can be tricky. Abnormal EKG sometimes can only be seen during exercise or while the symptoms are blooming. For these cases, ambulatory EKG or stress EKG is done. A stress EKG is a type of EKG used before, during and after exercise. Ambulatory EKG has a great mobility than the others, ambulatory EKG can monitor the heart for hours at a time to obtain a better result.

Sometimes doctors automatically schedule routine tests because they think that’s what patients expect.
