By examining the electrocardiogram, it is possible to detect the presence of disturbances in the production and conduct of electrical waves, which may be caused by a disturbance in the conduction system of the heart.

| Electrocardiogram |
Electrocardiography is an examination through which it is possible to identify how the electrical wave that regulates the work of the heart muscle is progressing, in addition, the occurrence of changes in the electrocardiogram may be an indication of the presence of a recent or old myocardial infarction, as it may indicate disorders caused by An imbalance in the level of salts in the body, or even drug poisoning, or disturbances in the normal work of the heart.
Patients who have previously had a heart attack or myocardial infarction, as well as patients who have been examined and found to have changes in their ECG, should always carry an ECG with them, in anticipation of the need for a comparison between this ECG and the new ECG and to determine whether these changes are old. or modern.
The at-risk category
This examination is performed for people suspected of having or suffering from tachycardia, myocardial infarction, cardiac arrest or any of the heart diseases in general.
How to perform the examination
In the electrocardiogram, the progress of the electrical wave that regulates the work of the heart muscle . This electrical wave is created in the natural pacemaker as it passes into the atria and causes them to contract, which contributes to blood flow from the atria to the ventricles.
Then the electrical wave passes special conduction fibers to the heart chambers, causing them to contract, which leads to blood flow from the left ventricle to the body tissues through the aorta, and blood flow from the right ventricle to the lungs.
Warnings
general
The risks associated with an ECG are small and rare. You won't feel anything during the ECG, but it can be uncomfortable when the sticky electrodes are removed. If the electrodes are left on too long, they can cause tissue to break or irritate the skin .
There may be other risks depending on your specific medical condition, so be sure to discuss any concerns with your doctor before taking the test.
During pregnancy:
There are no special caveats.
Breast feeding:
There are no special caveats.
Babies and Babies
There are no special caveats.
Elderly:
There are no special caveats.
Driving:
There are no special caveats.
Medicines that affect the test result
Medications to treat heart disorders such as digoxin can cause changes in the results of the electrocardiogram, and you must tell your doctor about all the medications you are taking before the test.
Analysis of the results
The results of the examination can be explained as follows:
Correct result: the waveform is normal.
Pathological result: The electrocardiogram appears abnormal, as it may indicate the following:
A disturbance in the rhythm of the heart’s work, such as: fast heartbeat or slow heartbeat.
Disruption of electrical conductivity.
Myocardial infarction.
Increase in the size of the ventricles or atria.
Pericarditis (Pericarditis).
heart attack.
