ECG or EKG or electrocardiography test is a simple and non-invasive test for the heart. Heart diseases can be detected by observing the ECG test report. The deviations in the heart waves as compared to the normal heart rhythm tells the doctors about various heart problems.
What is the Purpose of ECG?
Various heart diseases are detected by observing the deviations in heart waves of the patient’s ECG. Electrical signals from the heart are recorded by sticking ECG electrodes on different chest positions. These electrodes are connected to the computer system, which converts these electrical signals into waves that are represented as graphs on monitor screens. For further observation, these waves are recorded and printed on sheets as ECG reports to be studied by the doctor.
What is the procedure for ECG?
ECG test is a simple and non-invasive test. The procedure involves recording the electrical pulses of the heart.
- 1. Electrical signals from the heart are recorded by sticking ECG electrodes on different chest positions.
- 2. These electrodes are connected to the computer system, which converts these electrical signals into waves represented as graphs on monitor screens.
- 3. For further observation, these waves are recorded and printed on sheets as ECG reports to be studied by the doctor.

What are the heart’s electrical signals, and how are they generated?
The electrical signals are generated from a single point each time the heart beats and then spread gradually to the whole heart. These heartbeats lead to contractions and relaxations, which are essential to the heart’s functions because the movements help pump blood.
What are electrodes? What is the role of electrodes in ECG?
Electrodes are wired with sensors temporarily stuck on particular positions of the patient’s chest and lower limbs to sense and record the pulses. These electrodes are connected to the computer system, which convert these electrical signals into graphical representations. The graphical representations of ECG are represented in the form of waves of heart cycle. The doctor observes these heart waves and their irregularities to detect the type of heart problem.
Is ECG safe?
The ECG process is not invasive as the electrical signals are recorded from the surface area only without a single cut on the skin or taking blood out.
Electrocardiogram vs Electrocardiography
ECG, or electrocardiography, is a diagnostic technique to check heart problems. The report generated from an ECG test in a printed form is represented as a graph and is called an electrocardiograph.
Electrocardiography and electrocardiogram are not the same terms. The major difference is that electrocardiography is a procedure to record the heart’s activity, while the result of an electrocardiography procedure is produced as an electrocardiogram.
Conditions that can be diagnosed through ECG
Problems in heart functions lead to various heart diseases and cardiovascular conditions. Conditions that can be diagnosed through ECG are:
- 1. Heart attack
- 2. Heart failure
- 3. Cardiomyopathies
- 4. Coronary artery disease
- 5. Arrhythmias
-
Symptoms of heart problems:
Chest problems:
- 1. Pain in chest
- 2. Chest Tightness
- 3. Feeling pressure on the chest
- 4. Feeling heavy on the chest
- 5. Angina- chest discomfort
-
Pain in regions other than the chest
- 1. Neck pain
- 2. Jaw pain
- 3. Throat pain
- 4. Pain in the upper abdomen
- 5. Pain in back
-
Problems in lower limbs
- 1. Feeling Numb in my legs
- 2. Weakness in the legs
- 3. Pain in lower limbs (without cause)
-
Shortness of breath or heavy breathing
