An electrocardiogram is the cardiology test that records the electrical activity of the heart. Thus, it sets the rhythm of the heartbeat so that the cardiologist can interpret any arrhythmia, risk of heart attack and other pathologies.

 

What is an electrocardiogram?

electrocardiogram
This test is performed with a 12-lead electrocardiograph 

This test is performed using a 12-lead electrocardiograph , being a totally innocuous, simple test that requires very little time for it. In this way, it is a test suitable for any person, which simply consists of the patient lying on the table and hit a series of electrodes with suction cups or adhesives connected to the electrocardiograph. The patient does not have to do any previous preparation and during the test only has to be relaxed and breathe normally.

 

Results of an electrocardiogram

The information you need is very useful, since by recording the electrical activity of the heart you can detect the heart rhythm, the heart rate, if there is an increase in the size of cavities. It can help diagnose diseases such as arrhythmias, cardiomyopathies, angina, or heart attack.

If the results of the electrocardiogram are abnormal, it may be due to one of the following pathologies:

  • Impaired myocardium.
  • Arrhythmias.
  • Imbalances in the amount of calcium, potassium or other substances in the blood.
  • Congenital heart disease.
  • Increased heart volume.
  • Seizures after a previous cardiac arrest.
  • Cardiac arrest at the moment.
  • Scarce blood supply to the arteries.

 

When you need an electrocardiogram

An electrocardiogram should be performed on any patient who is aware of any symptoms such as chest pain , choking sensation or palpitations.

It is also recommended to perform the same in patients with risk factors such as hypertension and in elderly patients, given the higher prevalence of cardiovascular diseases at a greater age of the patient.
