What is an electrocardiogram?

The heart's function is to excite the blood in the lungs, where it is enriched with oxygen, and then the oxygenated blood promotes it to the other organs of the body. As the heart contracts and expands constantly, "low" electrical currents are produced. It records a special device called an electrocardiograph. This produces the electrocardiogram (ECG for short).

How is the test done?

The examination is carried out by placing special "wires" with their metal end (electrode) fixed to the skin with a painless "suction" mechanism. Electrodes (in the upper and lower limbs as well as in the chest wall) are used. Each of the electrodes reads the heart from its own angle, allowing the doctor to collect more information. Usually the examination lasts no longer than five minutes and is completely painless!

Is the ECG a dangerous test?

The ECG is absolutely safe!

What diseases can be diagnosed with ECG?

The ECG contributes decisively to the diagnosis of most heart conditions, such as coronary artery disease (myocardial ischemia), various arrhythmias, and others.
