Hi, guys. We have all heard about ECG. I know that it is very important in diagnosing various heart diseases. On the other hand, I don’t know what this method really does. What is shown on ECG exactly? I would really appreciate if anyone could help me with this. I hope someone will. Thanks.

Hi, there. Heart has an electrical activity. This activity is registered with electrodes of an ECG. Heart muscle has two phases in its electrical activity. Those are polarization and depolarization. Polarization of atria is registered as P wave. Polarization of ventricles is registered as QRS complex. Depolarization of ventricles is registered as T wave. Depolarization of atria cannot be registered since it is overlapped with polarization of ventricles, i.e. QRS complex. I hope this helps.
