Скачать или смотреть Why ECG (Electrocardiogram) is performed?

ECG, or electrocardiogram, is a simple test that can be used to check your heartbeats and electrical activity.
This test includes three main instruments: electrodes, wire, and an ECG machine.
Electrodes are attached to various parts of our chest, arms, and legs,
which are linked to an ECG machine through wires which shows waves.

The lengths of ECG waves are denoted by the letters P, Q, R, S, and T.
P, Q, R, S, T letters are used for the convenience and these represented on the ECG as a series of waves. These waves help us to understand heartbeat easily.

Why ECG Test is performed?
ECG can help diagnose certain heart conditions.
These heart defects include SA node malfunction, slow or fast heartbeat, heart attack,
pacemakers and medication that disrupts heart rhythm.

Sino-Atrial Nodes
The SA node, which is located on the right side of the heart, produces mild electric impulses.
These impulses control our heart contraction and relaxation.
If they do not function properly, our hearts do not contract and pump properly.
As a result, our heartbeat becomes abnormal.
This condition can be detected with ECG

Why our heartbeat gets slow and faster?
ECG can detect abnormally fast or slow heartbeats caused by exercise or stress.
Because these conditions are not continues. So, detecting them with ECG is difficult.
Theses conditions are detected by event monitor devices.
The event monitor is a portable ECG device that is attached to the patient's chest.
This device is activated by displaying heart symptoms caused by stress and exercise.
It records electric impulses, and it is usually placed for 30 days.


Heart Attack
If arteries in our heart gets blocked, this cause severe pain in our heart, which can lead to heart attack.
This type of conditions can be detected with ECG.
So we can find blood flow in our different parts of heart, and detect blockage in the heart.

Implanted Pace makers
Pacemaker devices are implanted in patients with slow heartbeat.
These devices generate mild electric impulses, and make our heartbeats normal.
Because the devices have been implanted for a long time, an ECG test is performed on a regular basis to detect their performance.
Heart medication
Medications used to treat heart defects or medications that have the potential to cause heart problems,
The ECG is then performed to detect any adverse effects of that medications on the heart.

Treatment
If an abnormal heartbeat is detected on an ECG, the test is usually repeated.
Also, an echo-cardiogram is performed to determine the exact cause of the abnormal heartbeat.
and then treat the patient as needed.
