The simple electrocardiogram (ECG at rest) is an easy, fast and painless examination, which is necessary and provides a lot of information about the function of the heart, thanks to the recording of the electrical activity of the heart.
With an ECG we can find out the normal function of the heart, the existence or non existence of an acute or subacute infarction or the possibility of an old infarction, the existence of permanent or temporary arrhythmias.
